High pressure magnetophotoluminescence in diluted magnetic semiconductors Cd1-xMnxSe and Cd1-xCoxSe 黒田, 規敬 95678 松田, 康弘 95679 Kuroda, Noritaka 95674 Matsuda, Yasuhiro 95675 428.8 diluted magnetic semiconductors magnetooptical effects electron correlation high pressure effects application/pdf 論文(Article) This paper reviews experimental studies on the magnetophotoluminescence in diluted magnetic semiconductors Cd1-xMnxSe with x = 0.01, 0.05, 0.10, and 0.25 and Cd1-xCoxSe with x = 0.012 at 1.4 and 4.2 K under hydrostatic pressures up to 2 GPa. The studies focus attention to the pressure dependence of the magnetic dichroism of the 1 s exciton state under magnetic fields of 0 to 27 T. Pressure strengthens the exciton-Mn(Co) and Mn(Co)-Mn(Co) exchange interactions. An analysis of these results in terms of the kinetic exchange theory shows that the on-site Coulomb energy U and the charge transfer energy ⊿ are reduced markedly by pressure. http://www.interscience.wiley.com/ journal article WILEY-VCH 1996-11 AM application/pdf Physica status solidi.
