Description

Magnetic fcc-Co75Ru25 (L12) phase and nonmagnetic fcc-Co25Ru75 (L12) phase are obtained by ion beam mixing in the respective Co-Ru multilayered films. Interestingly, in the Co50Ru50 multilayered films, a magnetic dual-fcc phase, identified to be a mixture consisting of a magnetic fcc-Co75Ru25 and a nonmagnetic fcc-Co25Ru75 phases, is observed at an irradiation dose of 3x1015 Xe+/cm2 and, upon further irradiation to a dose of 7x1015 Xe+/cm2, transformed into a nonmagnetic single-fcc phase with an alloy composition back to be Co50Ru50
