High Temperature Ferromagnetism in GaAs-based Heterostructures with Mn Delta Doping
A. M. Nazmul, T. Amemiya, Y. Shuto +2
We show that suitably-designed magnetic semiconductor heterostructures consisting of Mn delta-doped GaAs and p-type AlGaAs layers, in which the locally high concentration of magnet…

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…

High Ferromagnetic Transition Temperature (172K) in Mn delta-doped GaAs with p-type Selective Doping
Ahsan M. Nazmul, S. Sugahara, M. Tanaka
We have found high ferromagnetic transition temperature in Mn delta-doped GaAs-based heterostructures grown on GaAs(001) substrates by molecular beam epitaxy. A 0.3 ML Mn d-doped G…
