Transient Antiskyrmion‐Mediated Topological Transitions in Isotropic Magnets

Advanced Science, EarlyView.
A transient antiskyrmion‐mediated pathway that drives repeated stripe‐to‐skyrmion transitions is revealed, producing a net increase in topological charge in isotropic Dzyaloshinskii–Moriya interaction films. Experiments and simulations identify the antiskyrmion as a metastable excitation, enabling stochastic bitstream generation for probabilistic ...

Chromium and iron contained half-Heusler MnNiGe-based alloys

Journal of Magnetism and Magnetic Materials, 2015
Abstract The magnetic characteristics of chromium and iron containing MnNiGe-based alloys with several types of quenching and annealing were investigated. It was found that the quenched Mn0.89Cr0.11NiGe has a spontaneous and magnetic field induced magnetostructural first-order transitions at room temperature. These transitions might be accompanied by

Thermoelectric Property Mapping for High‐Performance Integrated MgAgSb‐MgCuSb System

Advanced Science, EarlyView.
From the property mapping of the MgAgSb–MgCuSb system, both thermoelectric materials and corresponding interface materials are optimized: Ag‐rich compositions provide higher PF and zT, whereas Cu‐rich side yields superior transport properties and low contact resistance.
