Elucidation of the helical spin structure of FeAs

Tom Lancaster, R. Schoonmaker, S.H. Lee, C.-H. Du, P. Steadman, J. Strempfer, Kh. A. Ziq, S.J. Clark, P.D. Hatton & T. Frawley
We present the results of resonant x-ray scattering measurements and electronic structure calculations on the monoarsenide FeAs. We elucidate details of the magnetic structure, showing the ratio of ellipticity of the spin helix is larger than previously thought, at 2.58(3), and reveal both a right-handed chirality and an out-of-plane component of the magnetic moments in the spin helix. We find that electronic structure calculations and analysis of the spin-orbit interaction are able to qualitatively account...

Probing interactions of thermal Sr Rydberg atoms using simultaneous optical and ion detection - Supporting Data

Ryan K. Hanley, Alistair D. Bounds, Paul Huillery, Niamh C. Keegan, Riccardo Faoro, Elizabeth M. Bridge, Kevin J. Weatherill & Matthew P.A. Jones
We demonstrate a method for probing interaction effects in a thermal beam of strontium atoms using simultaneous measurements of Rydberg EIT and spontaneously created ions or electrons. We present a Doppler-averaged optical Bloch equation model that reproduces the optical signals and allows us to connect the optical coherences and the populations. We use this to determine that the spontaneous ionization process in our system occurs due to collisions between Rydberg and ground state atoms in...

iGIMP: An implicit generalised interpolation material point method for large deformations (figure data)

T.J. Charlton, W.M. Coombs & C.E. Augarde
The Material Point Method (MPM) uses a combined Eulerian-Lagrangian approach to solve problems involving large deformations. A problem domain is discretised as material points which are advected on a background grid. Problems are encountered with the original MPM when material points cross between grid cells, and this has been tackled by the development of the Generalised Interpolation MPM, where material points' domains of influence extend beyond the currently occupied grid cell. In this paper, the...

Data Supporting 'Understanding the role of damping and Dzyaloshinskii-Moriya interaction on dynamic domain wall behaviour in platinum-ferromagnet nanowires', Scientific Reports 7: 4569 (2017)

A.T. Hindmarch
(Abstract from article) Heavy metal layers, exemplified by Pt, are known to play a significant role in the magnetization behaviour of thin-film ferromagnets by three distinct mechanisms that can each contribute to the reversal process. These include modifying the local magnetization state via an interfacial Dzyaloshinskii-Moriya interaction (IDMI), enhancement of the damping, via d-d hybridisation and spin-pumping across the interface, and the mediation of the magnetization switching, with the flow of current through a system,...

Spin-orbit coupled interferometry with ring–trapped Bose–Einstein condensates: supporting data

John L. Helm, Thomas P. Billam, Ana Rakonjac, Simon L. Cornish & Simon A. Gardiner
We propose a method of atom-interferometry using a spinor Bose–Einstein (BEC) and the well-established experimental technique of time-varying magnetic fields as a coherent beam-splitter. Our protocol creates long-lived superpositional counterflow states, which are of fundamental interest and can be made sensitive to both the Sagnac effect and magnetic fields on the sub micro-Gauss scale. We split a ring-trapped condensate, initially in the m f = 0 hyperfine sub-level, into superpositions of both internal spin state...

Magnetic trapping of SH radicals

Jack Eardley
Data showing magnetic trapping of SH radicals, produced via a process we call photostop. H2S in a skimmed, supersonic molecular beam was photodissociated to produce SH inside a 330 mK deep static magnetic trap. The molecular beam speed was controlled by the mixing ratio of H2S in Kr to match the recoil velocity of the SH photofragments such that some SH radicals were produced with near-zero laboratory-frame velocity. The density of SH radicals in the...

Supporting data: Mechanism for the uniaxial strain dependence of the critical current in practical REBCO tapes

Kozo Osamura, Shutaro Machiya & Damian Hampshire
Abstract form paper: In order to elucidate the effect of uniaxial strain on the critical current of practical REBCO tapes (REBa2Cu3O7−d , RE = Y and Gd) fabricated by Superpower and SuNAM, two types of critical current measurements were carried out. In the first, the tape sample was attached directly to a universal testing machine and pulled under a tensile load. In the second, the tape was soldered to a Cu–Be springboard and then attached...

Durham RCUK [Green] Open Access Data Year 2 (Aug2014-Jul2015)

Data listing all articles and conference papers published by a Durham author acknowledging RCUK funding between August 2014 and July 2015, which met the RCUK Open Access policy requirements via the Green OA route.

Durham RCUK [Green] Open Access Data Year 4 (Apr2016-Mar2017)

Frederick W F Foulds
NOTE: In early 2017, RCUK changed their 'compliance reporting' year to match their 'financial reporting' year, so that both reflected the period April 1st to March 31st each year. This means that part of this Year 4 data will overlap with the previous year 3 compliance data.

Fast native-MATLAB stiffness assembly for SIPG linear elasticity

R. Bird, W.M. Coombs & S. Giani
When written in MATLAB the finite element method (FEM) can be implemented quickly and with significantly fewer lines, when compared to compiled code. MATLAB is also an attractive environment for generating bespoke routines for scientific computation as it contains a library of easily accessible inbuilt functions, effective debugging tools and a simple syntax for generating scripts. However, there is a general view that MATLAB is too inefficient for the analysis of large problems. Here this...

Data and Software supporting Degiacomi et al study about a new method and associated software, DynamXL, that accommodates intrinsic protein dynamics in the modelling of cross-linking data. This approach substantially reduces error rates, leading to higher confidence in structure assessment and improved protein-protein docking.

SIPG fracture data supporting: A quasi-static discontinuous Galerkin configurational force fracture propagation method for brittle materials [IJNME (2017)]

R.E. Bird, W.M. Coombs & S. Giani
Abstract from paper: This paper presents a framework for r-adaptive quasi-static configurational force (CF) brittle crack propagation, cast within a discontinuous Galerkin (DG) symmetric interior penalty (SIPG) finite element scheme. Cracks are propagated in discrete steps, with a staggered algorithm, along element interfaces which align themselves with the predicted crack propagation direction. The key novelty of the work is the exploitation of the DG face stiffness terms existing along element interfaces to propagate a crack...

(C6F6)n- and (C6F6)I- Study Complete Dataset

Joshua Rogers & Cate Anstoter
The primary electron attachment process in electron driven chemistry represents one of the most fundamental chemical transformations with wide-ranging importance in science and technology. However, the mechanistic detail of the seemingly simple reaction of an electron and a neutral to form an anion remains poorly understood, particularly at very low electron energies. Here, time-resolved photoelectron imaging was used to probe the electron attachment process to a non-polar molecule using time-resolved methods. An initially populated diffuse...
