FePt Thin Films – Prospective Materials for Ultrahigh Density Magnetic Recording

Abstract

Constant increase of magnetic recording density requires application of modern ferromagnetic materials with high value of magnetic anisotropy constant and coercivity. Thin films on the bases of L10-FePt ordered phase is one of such materials. However, practical application of such materials requires to solve a number of materials science problems such as decrease of ordered phase formation temperature, formation of its predominantly oriented grains and increase of coercivity. Factors that affect structure formation and properties of FePt based films have been examined in this study. A number of modern studies aimed on solving problems mentioned above have been analyzed.
