Strain-controlled sign reversal of the anomalous Hall effect in Ru/[Co/Ni] multilayers
Jingying Zhang, Sigang Wang, Yue Xiang +4
The anomalous Hall effect (AHE) is a hallmark transport phenomenon in ferromagnets arising from relativistic spin-orbit interaction. Here, we report an unexpected sign reversal of…
Superconductivity Mediated Long Range Magnetic Coupling
Ming Yan Wang, Yi Liu, Yao Lu
We investigate a Rashba superconductor thin film coupled to overlaying ferromagnetic insulators (FIs). We show that the ferromagnetic insulators generate circular super-currents, e…
Synergistic doping of the grain interior and grain boundary alters deformation mechanisms and enables extreme strength in nanocrystalline Ni-Cr-Y alloys
Yi Liu, Jason R. Trelewicz, Timothy J. Rupert
Solid solution addition and grain boundary segregation have been independently shown to enhance the strength of nanocrystalline alloys. In the present study, the interplay between…
Disorder induced time-reversal-odd nonlinear spin and orbital Hall effects
Ruda Guo, Yi Liu, Cong Xiao +1
We develop a theory for the second-order time-reversal-odd (-odd) angular-momentum current, incorporating both spin and orbital components. We reveal that besides spin…
