Notes:
Zn1−xMnxSe films were grown by molecular-beam epitaxy on (100)-oriented GaAs, with Mn mole fraction varying from 0.06 to 0.22. All samples were characterized by x-ray diffraction. The Faraday rotations of Zn1−xMnxSe films was measured with polar Kerr apparatus in the 1.5–3.5 eV photon energy range at room temperature and 10 kG magnetic field. The Faraday spectra show two rotation peaks located at about 2.45 and 2.6 eV for all samples, and another peak located at about 2.74 eV appears for higher composition (x〉0.14) samples. The Mn2+ transitions shift toward the red with increasing Mn mole fraction. The Faraday rotations related to the interband transitions were not observed. The three Faraday rotations were due to the Mn2+ d–d* multiplet transitions: 6A1(6S)→4T2(4G) (∼2.45 eV); 6A1(6S)→4A1(4G) 4E(4G) (∼2.6 eV); and 6A1(6S)→4T1(4P) (∼2.72 eV), respectively. ©1997 American Institute of Physics.
