Control of current-induced spin-orbit effects in a ferromagnetic heterostructure by electric field
Ronghua Liu, WengLee Lim, Sergei Urazhdin
We study the effects of electrostatic gating on the current-induced phenomena in ultrathin ferromagnet/heavy metal heterostructures. We utilize heterodyne detection and analysis of…
Field-effect diode based on electron-induced Mott transition in NdNiO3
W. L. Lim, E. J. Moon, J. W. Freeland +4
We studied an electron-induced metal-insulator transition in a two-terminal device based on oxide NdNiO3. In our device, the NdNiO3 is electrostatically doped by the voltage applie…
Spectral Characteristics of the Microwave Emission by the Spin Hall Nano-Oscillator
R. H. Liu, W. L. Lim, S. Urazhdin
We utilized microwave spectroscopy to study the magnetization oscillations locally induced in a Permalloy film by a pure spin current, which is generated due to the spin Hall effec…
Temperature-dependent proximity magnetism in Pt
W. L. Lim, N. Ebrahim-Zadeh, H. G. E. Hentschel +1
We experimentally demonstrate the existence of magnetic coupling between two ferromagnets separated by a thin Pt layer. The coupling remains ferromagnetic regardless of the Pt thic…
Current-Induced Dynamics in Almost Symmetric Magnetic Nanopillars
Weng Lee Lim, Andrew Higgins, Sergei Urazhdin
Magnetic nanodevices usually include a free layer whose configuration can be changed by spin-polarized current via the spin transfer effect, and a fixed reference layer. Here, we d…
Dynamical Regimes Induced by Spin Transfer in Magnetic Nanopillars
Weng Lee Lim, Andrew Higgins, Sergei Urazhdin
We demonstrate the predicted out-of-plane precession induced by spin transfer in magnetic nanostructures with in-plane magnetic field. We show that other magnetic excitations have…
