PURPOSE: To prepare a magnetic garnet single crystal film, e.g. a Bi-substituted rare earth element-iron garnet film, which is hardly broken during growing, cooling or polishing, to provided a method for producing the same, and a Faraday rotor which can be produced in a high yield by using the magnetic garnet single crystal film which is hardly broken during growing,cooling or polishing. CONSTITUTION: In a method of producing a magnetic garnet single crystal film, which comprises growing a Bi-substituted magnetic garnet single crystal by applying a liquid-phase epitaxial growing method, the magnetic, garnet single crystal film is deposited while making the lattice constant of the magnetic garnet single crystal constant or gradually decreasing the lattice constant with the growth of a single crystal film and then increasing the lattice constant with the growth of the single crystal. |
