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…
Electron-Phonon Dephasing in Ultrathin Disordered Films: From Power Laws to Diagnostic Maps
Eugeniy Yu. Beliayev
Electron-phonon dephasing in ultrathin disordered metallic films is often summarized by a power law, . However, thin metals, alloys, and superconducting films…
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…
