Magnetic properties and domain structure of (Ga,Mn)As films with perpendicular anisotropy
, 2006 The ferromagnetism of a thin GaMnAs layer with a perpendicular easy anisotropy axis is investigated by means of several techniques, that yield a consistent set of data on the magnetic properties and the domain structure of this diluted ferromagnetic ...

Unconventional spin texture of a topologically nontrivial semimetal Sb(110) [PDF]
, 2012 The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture.

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, EarlyView.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Spectral Phasor Analysis for Brillouin Microspectroscopy
Frontiers in Physics, 2019 Brillouin Light Scattering (BLS) spectroscopy allows for the all-optical measurement of the hypersonic velocities in a sample, from which one can extract high-frequency elastic moduli. Recent advances in high resolution optical imaging spectrometers have

Temperature Dependence Of Brillouin Light Scattering Spectra Of Acoustic Phonons In Silicon [PDF]
, 2015 Electrons, optical phonons, and acoustic phonons are often driven out of local equilibrium in electronic devices or during laser-material interaction processes. The need for a better understanding of such non-equilibrium transport processes has motivated

Brillouin microscopy for the evaluation of hair micromechanics and effect of bleaching
Journal of Biophotonics, 2021 AbstractBrillouin microscopy is a new form of optical elastography and an emerging technique in mechanobiology and biomedical physics. It was applied here to map the viscoelastic properties of human hair and to determine the effect of bleaching on hair properties. For hair samples, longitudinal measurements (i.e. along the fibre axis) revealed peaks at
