Nature of magnetic coupling between Mn ions in as-grown GaMnAs studied by x-ray magnetic circular dichroism
Y. Takeda, M. Kobayashi, T. Okane +12
The magnetic properties of as-grown GaMnAs have been investigated by the systematic measurements of temperature and magnetic field dependent soft x-ray magnetic circu…
Magneto-optical properties of a new group-IV ferromagnetic semiconductor Ge1-xFex grown by low-temperature molecular beam epitaxy
Y. Shuto, M. Tanaka, S. Sugahara
A new group-IV ferromagnetic semiconductor, Ge1-xFex, was successfully grown by low-temperature molecular beam epitaxy (LT-MBE) without precipitation of ferromagnetic Ge-Fe interme…
A spin metal-oxide-semiconductor field-effect transistor using half-metallic-ferromagnet contacts for the source and drain
S. Sugahara, M. Tanaka
We propose and theoretically analyze a novel metal-oxide-semiconductor field-effect-transistor (MOSFET) type of spin transistor (hereafter referred to as a spin MOSFET) consisting…
External Control of Magnetism in Semiconductors at High Temperature (~100K)
Ahsan M. Nazmul, S. Kobayashi, S. Sugahara +1
We demonstrate the electrical and optical control of ferromagnetism in semiconductor heterostructures at high temperatures of 100-117 K. The heterostructures consist of Mn delta-do…
