La :YIG films are grown on gallium-gadolinium garnet (Gd<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub>) substrates from a supercooled melt-solution (MS) consisting of Y<sub>2</sub>O<sub>3</sub>, La<sub>2</sub>O<sub>3</sub>, and Fe<sub>2</sub>O<sub>3</sub> oxides and the PbO–B<sub>2</sub>O<sub>3</sub> solvent. In order to minimize the implantation of Pb<sup>2+</sup> ions into the films, which degrades the film quality, the epitaxy has to be performed at high temperatures and a low MS supercooling. It is found that, in order to maintain a constant growth rate of La :YIG films with reproducible parameters, a large MS mass (10–16 kg) has to be used, and the MS temperature has to be permanently lowered at a rate of 0.042 K/min.</p> ER -
