摘要：

We present a photoluminescence study of Cd//1// minus //xFe//xSe, a new diluted magnetic semiconductor (DMS). The luminescence spectrum was recorded as a function of temperature and applied magnetic field, revealing behavior which has significantly different from that observed in manganese based DMS. We conclude that Cd//1// minus //xFe//xSe exhibits Van Vleck paramagnetism instead of the more usual Larmor paramagnetism.
