Popis:	Garnet films of composition (BiYLu)3Fe5O12 have been grown on 〈111〉 Gd3Ga5O12, Sm3Ga5O12, and Nd3Ga5O12 substrates by liquid phase epitaxy. The larger lattice parameter substrates were used in order to increase the bismuth concentration in the films. The anisotropy Ku and the saturation magnetization 4πMs data are presented as a function of the Y/Lu ratio in the melt. The maximum anisotropy obtained was 1.5×105 erg cm−3 which is sufficient to support 0.5‐μm‐diameter bubbles. The ferromagnetic resonance linewidth at 10.1 GHz was measured to be less than 3 Oe. This allows for a domain wall mobility of 600 ms−1Oe−1 in a 0.5 μm bubble film.
