1. A method for producing a bismuth-substituted rare earth-iron-garnet single-crystal film in a mode of liquid-phase epitaxial growth, which comprises:
a step of putting a starting material composition for the bismuth-substituted rare earth-iron-garnet single-crystal film, Au and a flux composition into a crucible;
a step of heating and melting the starting material composition and Au to be a melt;
a step of cooling the melt to a temperature at which the bismuth-substituted rare earth-iron-garnet single-crystal film grows; and
a step of contacting the thus-cooled melt with a single-crystal film-growing substrate to thereby make the intended bismuth-substituted rare earth-iron-garnet single-crystal film grow on the substrate.
