Orthorhombic Magnetic Anisotropy in (EuBi)3Fe5O12 Garnet (110) Films

The effects of LPE growth conditions on Bi substitution and the previously reported large orthorhombic magnetic anisotropy in (EuBi)3Fe5O12 films are described. The results, with the anisotropy expressed in terms of Gyorgy´s parameters A and B, indicated that R1 (= Fe2O3/Eu2O3) and R3 (= PbO/B2O3) do not have so great an effect on the amount of Bi substitution as was previously believed, nor do they greatly influence the magnetic anisotropy. The growth temperature essentially determines the Bi substitution and resulting lattice mismatch.
