Magnetic field dependent impact ionization in InSb
Jinki Hong, Taeyueb Kim, Sungjung Joo +4
Carrier generation by impact ionization and subsequent recombination under the influence of magnetic field has been studied for InSb slab. A simple analytic expression for threshol…
Electric Control of Multiple Domain Walls in Pt/Co/Pt Nanotrack with Perpendicular Magnetic Anisotropy
Kab-Jin Kim, Jae-Chul Lee, Sang-Jun Yun +4
Electric control of multiple domain walls (DWs) motion is demonstrated by Pt/Co/Pt nanotracks with perpendicular magnetic anisotropy. Due to the weak microstructural disorders with…
Roles of adiabatic and nonadiabatic spin transfer torques on magnetic domain wall motion
Jae-Chul Lee, Kab-Jin Kim, Jisu Ryu +7
Electric current exerts torques-so-called spin transfer torques (STTs)-on magnetic domain walls (DWs), resulting in DW motion. At low current densities, the STTs should compete aga…
Universality between current- and field-driven domain wall dynamics in ferromagnetic nanowires
Jae-Chul Lee, Kab-Jin Kim, Jisu Ryu +7
Spin-polarized electric current exerts torque on local magnetic spins, resulting in magnetic domain-wall (DW) motion in ferromagnetic nanowires. Such current-driven DW motion opens…
Tunneling anisotropic magnetoresistance in multilayer-(Co/Pt)/AlOx/Pt structures
B. G. Park, J. Wunderlich, D. A. Williams +6
We report observations of tunneling anisotropic magnetoresitance (TAMR) in vertical tunnel devices with a ferromagnetic multilayer-(Co/Pt) electrode and a non-magnetic Pt counter-e…
Local Hall effect in hybrid ferromagnetic/semiconductor devices
Jinki Hong, Sungjung Joo, Tae-Suk Kim +5
We have investigated the magnetoresistance of ferromagnet-semiconductor devices in an InAs two-dimensional electron gas system in which the magnetic field has a sinusoidal profile.…
