Infrared Magneto-optic Measurement of Zn_(0.97)Co_(0.03)S Semimagnetic Semiconductor |

| Abstract: | The absorption spectra of ternary mixed crystal Zn0.97Co0.03.S SMSC have been measured by using a Fourier transform spectrometer and a high field sup3rconducting magnet.The absorption lines shift or split when magnetic field is added. The widthes and the positions of lines also change with temperature. These phenomena can be interpreted by S-L interaction of d-electrons in Co2+ and Jahn-Teller effect because of coupling between electrons, vibration modes of Co2+ and their neighborhood atoms. The absorption spectra of samples with different Co concentrations are also measured at different temperature, and the phenomena are well discussed. |
