.) amorphous films with perpendicular magnetic anisotropy had been deposited onto water cooled substrate by a rf magnetron sputtering system with a negative bias voltage. the temperature dependence of magneto-optical properties of Sm32Dy2CQ66 film had been studied. We had studied the influence of magneto-optical recording parameters on the recording domain size of Sm32Dy2CQ66 film, and calculated its minimum of stable domain size. The results show that the. SmCoDy amorphous films with
