Highly Bi‐substituted garnet films (BiLu)3Fe5O12 (Bi=0.89/f.u.) have been grown on (111)‐oriented Gd3Ga5O12 substrates by liquid‐phase epitaxy with only Bi2O3 as a flux. The specific Faraday rotation θF attains −0.14 deg/μm at 1.3 μm. Guided‐optical‐wave propagation loss of 0.6 dB/cm at 1.3 μm is obtained by doping an appropriate amount of MgO in the melt. Magnetostatic backward volume wave (MSBVW) is launched efficiently into the film as expected from the measured small ferromagnetic resonance… Expand
