Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Magnetic Properties of One-Dimensional Quasiperiodic Co/Pt Multilayers

, 2006
We have fabricated Fibonacci [Co/Pt] multilayers with two constituent Co/Pt bilayers, as well as periodic multilayers of the same Co/Pt bilayers, all of which exhibit perpendicular magnetic anisotropy.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Magnetism in Pt/Co/Cu multilayers: dependence on Co thickness and the influence of additional superconducting Nb layers

Materials Research Express
We report sputtered [Pt/Co( d _Co )/Cu] _×15 multilayers and their integration with superconducting Nb. Tuning the Co thickness d _Co  = 0.6–1.2 nm transforms nearly square perpendicular hysteresis into wasp-waisted switching, while room-temperature ...
