<P>PROBLEM TO BE SOLVED: To provide a low resistant and highly efficient spin injection element by highly orienting a barrier film having a small band gap in a direction (001) of a rock-salt structure. <P>SOLUTION: A tunnel magnetoresistance effect element 1 is formed by laminating a base film 300, a nonmagnetic seed film 310, a ferromagnetic film 305, a barrier film 307, a ferromagnetic film 308, and a protective film 309. For the nonmagnetic seed film 310, a material of face-centered cubic lattice whose lattice constant is smaller than √2 times of a lattice constant of the ferromagnetic film 305. <P>COPYRIGHT: (C)2013,JPO&INPIT |
