Round robin comparison on quantitative nanometer scale magnetic field measurements by magnetic force microscopyXiukun Hu
As a standard tool for nano-scale investigation of magnetic domain structures, magnetic force microscopy (MFM) measures the local stray magnetic field landscape of the measured sample, however, generally providing only qualitative data. To quantify the stray magnetic fields, the MFM system could be calibrated by a so-called transfer function (TF) approach which fully considers the finite extent of the MFM tip. However, albeit being comprehensive, the TF approach is not yet well established, mainly due...

Dataset for the publication \"A Ti/Pt/Co Multilayer Stack for Transfer Function Based Magnetic Force Microscopy Calibrations summary\"Baha Sakar, Sibylle Sievers, Alexander Fernández Scarioni, Felipe García-Sánchez, Ilker Öztoprak, Hans Werner Schumacher & Osman Öztürk
Magnetic force microscopy (MFM) is a widespread technique for imaging magnetic structures with a resolution of some 10 nanometers. MFM can be calibrated to obtain quantitative (qMFM) spatially resolved magnetization data in units of A/m by determining the calibrated point spread function of the instrument, its instrument calibration function (ICF), from a measurement of a well-known reference sample. Beyond quantifying the MFM data, a deconvolution of the MFM image data with the ICF also corrects...

Dataset for the publication \"Using a Tip Characterizer to Investigate Microprobe Silicon Tip Geometry Variation in Roughness Measurements\"Min Xu, Ziqi Zhou, Thomas Ahbe, Erwin Peiner & Uwe Brand
Given their superior dynamics, microprobes represent promising probe candidates for high-speed roughness measurement applications. Their disadvantage, however, lies in the fact that the volume of the microprobe’s silicon tip decreases dramatically during roughness measurement, and the unstable tip geometry leads to an increase in measurement uncertainty. To investigate the factors that influence tip geometry variation during roughness measurement, a rectangular-shaped tip characterizer was employed to characterize the tip geometry, and a method for reconstructing the...

Dataset for Combining Harmonic Laser Beams by Fiber Components for Refractivity–Compensating Two-Color InterferometryXiukun Hu, Anni Röse, Günther Prellinger, Paul Köchert, Jigui Zhu & Florian Pollinger
A perfect spatial overlap with multiple beams of different wavelengths is a prerequisite for multi–wavelength interferometry. Beam combination with the help of fibers seems to be an interesting method for this. We investigated three different types of fiber components, multi–mode wavelength division multiplexers (MM–WDMs), single–mode wavelength division multiplexers (SM–WDMs), and endlessly single–mode polarization maintaining photonic crystal fibers (PM–PCFs). All three seem potential candidates for a perfect spatial overlap of laser beams separated by an octave,...
