Reconfigurable Current Distributions in Percolating Au Films and CrO2 Powder Compacts - Beyond Geometrical Connectivity
E. Yu. Beliayev, I. G. Mirzoiev, V. A. Horielyi
Despite fundamental differences in morphology, dimensionality, and microscopic transport, semicontinuous Au films and compacted CrO2 powders converge on a common network-level prin…
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…
