| Abstract: | We characterized in-plane magnetic and electrical properties of MnAs/InAs/GaAs(111)B hybrid structure grown by molecular beam epitaxy (MBE). We observed isotropic easy magnetization in two crystallographic in-plane directions, [2^^-110] and [01^^-10] of hexagonal MnAs i.e. [1^^-10] and [11^^-2] of cubic InAs. We also fabricated transmission line model (TLM) devices, and observed almost isotropic electrical properties in two crystallographic in-plane directions, [1^^-10] and [11^^-2] of cubic InAs. Also we tried to fabricate and characterize lateral spin-valve (LSV) devices from the hybrid structure. We could roughly estimate the spin injection efficiency and the spin diffusion length at room temperature in [11^^-2] direction. We believe that the hybrid structures are helpful to design spintronic device with good flexibility in-plane. |
