| Research Abstract |
The purpose of this study is to induce strain to FeCo thin films and to investigate the influence of the strain for the coercivity.
1. FeCo layer grew epitaxially on the Rh(001) buffered layer. After annealing, coercivity increased and lattice distortion of FeCo was observed at the Rh/FeCo interface.
2. Rh/FeCo-X, Rh/FeCo-X-N films (X=V, Cr, Zr, Sn) were prepared to induce some strain into FeCo layer on Rh buffered layer. The c/a increased for FeCo-X-N films, and the maximum value of c/a reached to 1.05. The film showed anisotropic hysteresis loops.
