Doped YAG nanoparticles: neutron diffraction to explain luminescent properties by the lattice features

, , , &
Doped YAG is an important material with interesting technological applications in inorganic electroluminescence displays, X-ray scintillators, etc. In order to control the morphology and particle size of products, we modified the preparation methods by adding some additives (polymers, metals and glasses), thus improving the luminescent properties. Particularly, one of the most interesting and puzzling result is that, when dealing with nano-powders with the same particle size, we observed the same emission spectra but values of...

Magnetic anisotropy and crystal structure distortions in ErB4

, , &
We propose to investigate the unusual low-temperature behaviour of single crystal ErB4 in an applied magnetic field. At room temperature, the compound has a tetragonal structure in which the magnetic Er ions form a network of squares and triangles in that maps to the Shastry-Sutherland lattice, a rare example of highly frustrated system with an exact ground state solution. It has recently been found through the magnetisation and magnetostriction measurements that a significant anisotropy of...

Magnetic structure of a new quantum magnet

, &
CaCuTe2O6 belongs to the family of ACuTe2O6 that consists of a 3-dimensional arrangement of spin-1/2 Cu ions. Three main interactions are relevant in the system where the first neighbor interaction (J3) couples the Cu ions into isolated triangles, the second (J2) couples them into the highly frustrated hyperkagome lattice consisting of corner sharing triangles and the third neighbor interaction (J3) couples them into antiferromagnetic chains. J3 dominates the magnetism of CaCuTe2O6 where antiferromagnetic chains are...

Interplay between magnetism and superconductivity in the FeYSr2Cu2Oy iron substituted cuprate

, , , , , &
We want to address the problem of a possible coexistence of superconductivity and magnetism in the FeSr2YCu2Oy cuprate by means of a combined ZF/TF-muSR study. This compound presents a laminar ordering of copper and iron along the crystallographic c axis, allowing the study of the iron oxidation state effect in the superconducting and magnetic properties of this material. We have observed a progressive evolution from a magnetic parent compound at low doping levels to a...
