PROBLEM TO BE SOLVED: To realize a desired supersaturation temperature in a few repetition by growing a Bi-substituted iron garnet film under specific conditions from a melt of a certain composition on a specified substrate. SOLUTION: Using a melt of a certain composition, a Bi-substituted iron garnet film is subjected to liquid phase epitaxial growth on a specified substrate. The supersaturation temperatureΔT defined as the difference between saturated temperature Ts and the growth temperature To at which the respective lattice constants of the substrate and the garnet film coincide with each other in the above epitaxial growth process is determined. When theΔT is out of a specified temperature range, at least one parameter of the two: R3 and RBi , defined as R3 =PbO/B2 O3 and RBi =Bi2 O3 /ζR2 O3 (R is Y or a rare earth element), is increased or decreased so thatΔT falls within the specified temperature range.
