 note = {application/pdf, 論文(Article), Magnetophotoluminescence due to the A exciton has been studied in a diluted magnetic semiconductor Cd0.95Mn0.05Se under hydrostatic pressures of 0–2 GPa at 1.4 K. The experimental data on the pressure dependencies of the hole-Mn p-d and Mn-Mn d-d exchange interactions suggest that in concurrence with an increase in the p-d transfer integral the on-site Coulomb energy U and p-d charge-transfer energy Δ decrease with increasing pressure. The deduced value, dlnU/dP  =  -2.5×10-2 GPa-1, of the relative pressure coefficient of U is about 4 times in magnitude as great as the linear compressibility of lattice., 代表的な希薄磁性半導体の一つであるCd0.95Mn0.05SeのA励起子のフォトルミネッセンスを複合極限条件下で詳しく測定した。この測定により、世界で初めてp-d交換結合と最隣接 d-d 超交換結合がそれぞれに加圧とともに増大して行く様子を直接かつ独立に観察することができた。これらの交換結合定数に運動交換結合理論を適用して有効オンサイト・クーロンエネルギー U および電荷移動エネルギー Δ を評価した結果、p 価電子が軌道混成を通してd 電子の電子相関を遮蔽する様子が明瞭に捉えられた。, http://link.aps.org/abstract/PRL/v77/p1111},
