The relationship between the magnetic properties of Co-Cr-Pt film and the film’s surface morphology was investigated in terms of the differences in surface free energy and interatomic distance between the Co and the underlayers. It was found that high perpendicular coercivity was obtained in the film structure where it was flat and smooth and grain separation had begun to occur. Moreover, the surface free energy was found to be one of the factors controlling not only the film surface morphology, but also the crystal orientation.
