Four series of /110/ GdBi garnet film bubble memory media with orthorhombic anisotropy were grown on /110/ Nd/sub 3/Ga/sub 5/O/sub 12/ garnet substrates. The orthorhombic anisotropy energy differences K..mu.. ((110) to (001)) and K/sub rho/ ((110) to (110)) were calculated from the anisotropic magnetic field and the 4..pi..Ms value. Values were thus obtained for parameters A and B in Gyorgy's two-parameter model. Calculations of the growth-induced component of the Gyorgy parameters A and B as functions of growth temperature showed that, in the fourth series of films, Bo/sup 110/ and Bo/sup 111/ were identical. Up to now, Bo/sup 110/ and Bo/sup 111/ have the same values only for (YBi)/sub 3/ (FeGa)/sub 5/O/sub 12/. 3 ..mu..m-diameter bubble material was obtained using the third series of films.
