The electronic structure of doped Mn in (Ga,Mn)As is studied by resonant inelastic X-ray scattering (RIXS). From configuration-interaction cluster-model calculations, the line shapes of the Mn $L_3$ RIXS spectra can be explained by $d$-$d$ excitation

Nature of magnetic coupling between Mn ions in as-grown Ga$_{1-x}$Mn$_{x}$As studied by x-ray magnetic circular dichroism

Autor: Takeda, Y., Kobayashi, M., Okane, T., Ohkochi, T., Okamoto, J., Saitoh, Y., Kobayashi, K., Yamagami, H., Fujimori, A., Tanaka, A., Okabayashi, J., Oshima, M., Ohya, S., Hai, P. N., Tanaka, M.

The magnetic properties of as-grown Ga$_{1-x}$Mn$_{x}$As have been investigated by the systematic measurements of temperature and magnetic field dependent soft x-ray magnetic circular dichroism (XMCD). The {\it intrinsic} XMCD intensity at high tempe

Quantum-size effect and tunneling magnetoresistance in ferromagnetic-semiconductor quantum heterostructures

Autor: Ohya, S., Hai, P. N., Mizuno, Y., Tanaka, M.

We report on the resonant tunneling effect and the increase of tunneling magnetoresistance (TMR) induced by it in ferromagnetic-semiconductor GaMnAs quantum-well heterostructures. The observed quantum levels of the GaMnAs quantum well were successful
