Ion irradiation and thermally induced mixing of CoCrPt∕Cr multilayered films

Abstract

A set of
multilayered films with variable layer thicknesses has been used in an investigation of interlayer mixing and “patterning” of samples with relatively high coercivity and in-plane magnetization. The multilayers with the highest coercivities were irradiated with different doses of
ions in order to intermix the Cr and CoCrPt layers and push the CoCrPt stoichiometry into the nonmagnetic region of the phase diagram. Samples were also irradiated through a Ni-grating mask to obtain patterning by adjacent magnetic and nonmagnetic regions of the film. Thermal annealing experiments mirrored the change in magnetic properties of the irradiated samples.
