Observation of the orbital Hall effect in a light metal Ti
Young-Gwan Choi, Daegeun Jo, Kyung-Hun Ko +7
The orbital angular momentum is a core ingredient of orbital magnetism, spin Hall effect, giant Rashba spin splitting, orbital Edelstein effect, and spin-orbit torque. However, its…
Influences of interfacial oxidization on surface magnetic energy, magnetic damping and spin-orbit-torques in Pt / ferromagnet / capping structures
DongJoon Lee, WonMin Jeong, DeokHyun Yun +6
We investigate the effect of capping layer (CAP) on the interfacial magnetic anisotropy energy density (K_S), magnetic damping (α), and spin-orbit torques (SOTs) in heavy-metal (Pt…
Thermal spin injection and accumulation in CoFe/MgO tunnel contacts to n-type Si through Seebeck spin tunneling
Kun-Rok Jeon, Byoung-Chul Min, Seung-Young Park +4
We report the thermal spin injection and accumulation in crystalline CoFe/MgO tunnel contacts to n-type Si through Seebeck spin tunneling (SST). With the Joule heating (laser heati…
Electrical Investigation of the Oblique Hanle Effect in Ferromagnet/Oxide/Semiconductor Contacts
Kun-Rok Jeon, Byoung-Chul Min, Youn-Ho Park +2
We have investigated the electrical Hanle effect with magnetic fields applied at an oblique angle (θ) to the spin direction (the oblique Hanle effect, OHE) in CoFe/MgO/semiconducto…
Threshold current for switching of a perpendicular magnetic layer induced by spin Hall effect
Ki-Seung Lee, Seo-Won Lee, Byoung-Chul Min +1
We theoretically investigate the switching of a perpendicular magnetic layer by in-plane charge current due to the spin Hall effect. We find that, in the high damping regime, the t…
Effect of spin relaxation rate on the interfacial spin depolarization in ferromagnet/oxide/semiconductor contacts
Kun-Rok Jeon, Byoung-Chul Min, Youn-Ho Park +4
Combined measurements of normal and inverted Hanle effects in CoFe/MgO/semiconductor (SC) contacts reveal the effect of spin relaxation rate on the interfacial spin depolarization…
Electrical spin injection and accumulation in CoFe/MgO/Ge contacts at room temperature
Kun-Rok Jeon, Byoung-Chul Min, Young-Hun Jo +5
We first report the all-electrical spin injection and detection in CoFe/MgO/moderately doped n-Ge contact at room temperature (RT), employing threeterminal Hanle measurements. A si…
