Abstract
We have succeeded in preparing good quality epitaxial CoCrPt thin films on different substrates (Al2O3, LaAlO3, SrTiO3 and MgO) with the c-axis perpendicular to the substrate plane and magnetic properties were investigated. Magneto-optical spectra of the CoCrPt films prepared under different conditions were measured at room temperature between 1.2 and 6 eV, to investigate the physical properties of these films from the fundamental point of view.
