Role of spin mixing conductance in spin pumping: enhancement of spin pumping efficiency in Ta/Cu/Py structures
Praveen Deorani, Hyunsoo Yang
From spin pumping measurements in Ta/Py devices for different thicknesses of Ta, we determine the spin Hall angle to be 0.021 - 0.033 and spin diffusion length to be 8 nm in Ta. We…
Spin-orbit torques in Co/Pd multilayer nanowires
Mahdi Jamali, Kulothungasagaran Narayanapillai, Xuepeng Qiu +3
Current induced spin-orbit torques have been studied in ferromagnetic nanowires made of 20 nm thick Co/Pd multilayers with perpendicular magnetic anisotropy. Using Hall voltage and…
A new route to spin-orbit torque engineering via oxygen manipulation
Xuepeng Qiu, Kulothungasagaran Narayanapillai, Yang Wu +6
Spin transfer torques allow for electrical manipulation of magnetization at room temperature, which is utilized to build future electronic devices such as spin transfer torque memo…
Conductance modulation in topological insulator Bi2Se3 thin films with ionic liquid gating
Jaesung Son, Karan Banerjee, Matthew Brahlek +5
A Bi2Se3 topological insulator field effect transistor is investigated by using ionic liquid as an electric double layer gating material, leading to a conductance modulation of 365…
Nonreciprocity engineering in magnetostatic spin waves
Praveen Deorani, Jae Hyun Kwon, Hyunsoo Yang
Magnetostatic surface spin waves (MSSW) excited from a coplanar waveguide antenna travel in different directions with different amplitudes. This effect, called nonreciprocity of MS…
Giant magnetoresistance in single layer graphene flakes with a gate voltage tunable weak antilocalization
Kalon Gopinadhan, Young Jun Shin, Indra Yudhistira +2
A clear gate voltage tunable weak antilocalization and a giant magnetoresistance of 400 percent are observed at 1.9 K in single layer graphene with an out-of-plane field. A large m…
