Abstract

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