Spin-Related Current Suppression in a Semiconductor-Quantum-Dot Spin-Diode Structure
K. Hamaya, M. Kitabatake, K. Shibata +6
We experimentally study the transport features of electrons in a spin-diode structure consisting of a single semiconductor quantum dot (QD) weakly coupled to one nonmagnetic (NM) a…
Out-of-plane magnetization reversal processes of (Ga,Mn)As with two different hole concentrations
K. Hamaya, T. Taniyama, Y. Yamazaki
We study magnetization reversal processes of in-plane magnetized (Ga,Mn)As epilayers with different hole concentrations in out-of-plane magnetic fields using magnetotransport measu…
Effect of the shape anisotropy on the magnetic configuration of (Ga,Mn)As and its evolution with temperature
K. Hamaya, T. Taniyama, T. Koike +1
We study the effect of the shape anisotropy on the magnetic domain configurations of a ferromagnetic semiconductor (Ga,Mn)As/GaAs(001) epitaxial wire as a function of temperature.…
Mixed magnetic phases in (Ga,Mn)As epilayers
K. Hamaya, T. Taniyama, Y. Kitamoto +1
Two different ferromagnetic-paramagnetic transitions are detected in (Ga,Mn)As/GaAs(001) epilayers from ac susceptibility measurements: transition at a higher temperature results f…
