摘要：
A 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 basis of L1(0)-FePt ordered phase is one of such materials. However, practical application of such materials requires solving a number of materials science problems such as the decrease of ordered phase formation temperature, formation of its predominantly oriented grains and the 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.
