Low-Temperature Magnetoresistance Hysteresis in Granular Cr1-xFexO2: Slow Relaxation of Transport-Active Magnetic Configurations
E. Yu. Beliayev, V. A. Horielyi, I. G. Mirzoiev +1
Low-temperature magnetoresistance loops of compacted CrO2 powders become strongly nonmonotonic when electrical transport is dominated by a small number of spin-dependent intergranu…
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…
Vertically Correlated Disorder and Structured Interlayer Tunneling in Cuprates
E. Yu. Beliayev, Y. K. Mishra, I. G. Mirzoiev +2
Cuprate superconductors display robust in-plane electronic correlations but exceptionally fragile interlayer coherence. We suggest that even weak vertically correlated disorder (ar…
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…
