Abstract

Zn1-xMnxO (x=0-0.061) thin films were grown by molecular beam epitaxy (MBE) system. Transmit-tance shows an increase of the band gap with the increasing Mn concentration. Resonant Raman scattering (RRS) spectra showed 11 longitudinal optical phonon lines for the Zn1-xMnxO samples. For the Zn0.997Mn0.003O sample, circular polarization degree of 9% was observed at magnetic field B = 5T. The dependence of circular polarization rate on the magnetic field intensity exhibits Brillouin type para-magnetism.
