fct Fe-Ni-N薄膜の構造と飽和磁化  [in Japanese] Structure and Saturation Magnetization for fct Fe-Ni-N Films  [in Japanese]

Fe-Ni-N films were fabricated on MgO{100}single-crystal substrates by dc facing-targets sputtering. Structural analysis and magnetic measurement were carried out. The results can be summarized as follows: (1) an Fe-Ni-N phase with fct structure and 11 at% N can be formed in a wide Ni content range from 20 to 40at%; (2) N atoms are located at the body center of the fct structure; (3) judging from the dependence of the saturation magnetization for fct Fe-Ni-N films with 11at% N on the Ni content, it is suggested that the fct phase does not strogly affect the appearance of giant magnetic moment in Fe-N films.
