Paper Abstract

Cu-doped Bi, Ga:DyIG and Bi, Al:DyIG films on glass substrates have been prepared by pyrolysis method, and the coercive force (Hc) and the compensation temperature (Tcomp) were investigated. For Cu-doped Bi, Ga:DyIG and Bi, Al:DyIG films, high Hc values of 13 kOe and 7 kOe were obtained, respectively. The extremely high Hc values were attributed to Cu entering the lattice sites.
