摘要：
Magneto-optical properties of a ferromagnetic semiconductor (Zn,Cr)Te were investigated through magnetic circular dichroism (MCD) measurements in the visible spectral range. (Zn,Cr)Te films without and with an additional nitrogen (N) doping as an acceptor exhibited different MCD spectra around the F point; a broad MCD band extending over a few hundred meV was observed in the undoped (Zn,Cr)Te while a relatively sharp peak appeared in the heavily N-doped (Zn,Cr)Te. The different MCD spectra are considered to be correlated with the change in the Cr valence state due the acceptor doping.
