Abstract
The magnetic and magnetooptical properties of CeFeO3(CFO) and YCeCoFeO6(YCFCO) films grown by pulsed laser deposition onto MgO or SrTiO3(100) substrates at ~10-5 Torr or at 6 mTorr O2 are studied. Faraday rotation hysteresis loops were obtained at the 1.55-mum wavelength, yielding a saturation of ~0.6 deg/mum in all CFO films and ~0.25 deg/mum in the YCFCO film grown under vacuum. Optical measurements give a refractive index of 2.9 and an optical absorption of 1.8 dB/mum at the same wavelength. The corresponding saturation magnetization in CFO films reaches 45 emu/cm3 at room temperature. Interpretation of the magnetic and magnetooptical properties is based on the electronic structure and optical transitions of Ce3+ in an iron garnet or orthoferrite lattice
