Transport and relaxation of current-generated nonequilibrium phonons from nonlocal electronic measurements
Guanxiong Chen, Sergei Urazhdin
We study phonons generated by current in a Pt nanowire, by measuring resistance of another nanowire separated from the first one by an insulating spacer. For thin spacers, the resi…
Exchange bias without directional anisotropy in Permalloy/CoO bilayers
Alexander Mitrofanov, Guanxiong Chen, Alexander Kozhanov +1
We utilize transverse ac susceptibility measurements to characterize magnetic anisotropy in archetypal exchange-bias bilayers of ferromagnet Permalloy (Py) and antiferromagnet CoO.…
Ideal memristor based on viscous magnetization dynamics driven by spin torque
Guanxiong Chen, Sergei Ivanov, Sergei Urazhdin
We show that ideal memristors - devices whose resistance is proportional to the charge that flows through them - can be realized using spin torque-driven viscous magnetization dyna…
Experimental demonstration and analysis of random field effects in ferromagnet/antiferromagnet bilayers
Guanxiong Chen, Dylan Collette, Sergei Urazhdin
More than 30 years ago, Malozemoff (Phys. Rev. B 35, 3679 (1987)) hypothesized that exchange interaction at the interface between a ferromagnet (F) and an antiferromagnet (AF) can…
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…
