【摘要】 在７３～３００Ｋ温度范围内，首次测量了不同组分的新型稀磁半导体Ｚｎ＿（１－ｘ）Ｃｏ＿ｘＳ（ｘ＝０．００１，０．０１，０．０３，０．０４８，０．０５３，０．０６３）的近红外和可见区的吸收光谱和磁圆二色谱。观测到一系列吸收峰和磁圆二色谱峰，两者互相对应，其峰位与样品组分ｘ值无关。它们分别对应于Ｃｏ￣（２＋）离子在Ｔ＿ｄ对称的晶体场中不同能级间的跃迁。更多还原

【Abstract】 Absorption and Magnetic Circular Dichroism （MCD ） spectra have been measured in a new diluted magnetic semiconductor Zn_1-xCo_xS（with x=0. 001,0. 01,0. 03,0. 048,0. 053 and 0. 063）at temperature 73K to 300K in visible and near in-frared region respectively for the first time.A series of absorption and MCD spectra have been observed. Both of the spectra are in good agreement and the peaks are in-dependent on the composition of sample and corresponding to the transitions between the different energy levels of Co￣（2+）ion in a crystal field of T_d symmetry.更多还原
