Observation of anomalous non-Ohmic transport in current-driven nanostructures
Guanxiong Chen, Ryan Freeman, Andrei Zholud +1
Sufficiently large electric current applied to metallic nanostructures can bring them far out-of-equilibrium, resulting in non-Ohmic behaviors characterized by current-dependent re…
Measurement of the Hall effect at nanoscale with three probes
G. X. Chen, R. X. Cao, A. Zholud +1
The Hall effect and its varieties such as quantum, anomalous, and spin Hall effects, provide indispensable tools for the characterization of electronic and magnetic properties of m…
Intrinsic and extrinsic contributions to spin scattering in Pt
Ryan Freeman, Andrei Zholud, Zhiling Dun +2
We utilize nanoscale spin valves with Pt spacer layers to characterize spin scattering in Pt. Analysis of the spin lifetime determined from our measurements indicates that the extr…
Spin transfer due to quantum fluctuations of magnetization
Andrei Zholud, Ryan Freeman, Rongxing Cao +2
Spin transfer - the transfer of angular momentum from spin-polarized electrical current to magnetic materials - has been extensively researched as an efficient mechanism for the el…
