Transport-Weighted Coercivity in Granular CrO2: Why Magnetoresistance and Magnetization Can Disagree
E. Yu. Beliayev, I. G. Mirzoiev, V. A. Horielyi +1
Magnetoresistance hysteresis is often used to estimate the coercive field of a magnetic material. We reanalyse our published magnetotransport and magnetometry data on compacted pow…
Emergent Coherence at the Edge of Magnetism: Low-Doped La2-xSrxCuO4+delta Revisited
E. Yu. Beliayev, Y. K. Mishra, I. A. Chichibaba +3
The La2-xSrxCuO4+delta (LSCO) system provides a unique experimental setting for exploring how magnetism, superconductivity, and disorder jointly shape charge transport in a doped M…
Electron Transport in Compacted Powders of VO2 Nanoparticles: Variable Range Hopping vs Percolation Behavior
E. Yu. Beliayev, Yogendra Kumar Mishra, Horst-Gunter Rubahn +4
Electron transport properties in compacted VO2 nanopowders were studied. While VO2 usually exhibits a first-order metal-insulator transition (MIT) at ~340K, in our compressed nanop…
Changes in the coercivity fields of magnetoresistance hysteresis loops under the influence of a spin-polarized current
E. Yu. Beliayev, I. G. Mirzoiev, V. V. Andrievskii +4
Using the example of a pressed sample consisting of chromium dioxide nanoparticles coated with insulating shells, we study the relationship between the electronic transport system…
