Solid-State Synthesis of Co-Sm(110) Epitaxial Films with Large Magnetocrystalline Anisotropy

Article Preview

Abstract:

Solid-state synthesis of a Sm2Co7 (110) hard magnetic phase prepared by successive deposition of Co and Sm layers onto a MgO(001) surface at a temperature of 400 С has been experimentally studied. Upon annealing at 500 С, the structure of the material changes, which leads to the formation of an epitaxial Sm2Co17 (110) phase. The first and second magnetocrystalline anisotropy constants of the Co-Sm have been determined.
