Fe100-xPtx alloy films were fabricated by controlled ion beam sputtering, and the evolution of L10 ordering during annealing was studied. The findings have implications for the fabrication of future recording media materials.
Fe100-xPtx alloy films are fabricated by controlled ion beam sputtering. Composition of the films was tuned by varying the relative atomic percentage of iron and platinum via controlling the area exposed to the ion beam. Structural and magnetic properties of films are studied using x-ray reflectivity, x- ray fluorescence, x-ray diffraction and Magneto Optic Kerr Effect. Isochronal annealing of films was done at 500 degrees C for 1 hour. Evolution of L10 ordering upon thermal annealing is investigated and correlation with the relative atomic percentage has been observed and explained. The finding of the work is useful for the fabricating the future recording media material. Copyright (c) 2022 Elsevier Ltd. All rights reserved.
