| Abstract: | The preparation and magneto optic recording characteristics of amorphous SmDyFeCo thin film are studied. It has been found that the size of the recording domain of the film is smaller than that of the DyFeCo thin film. It is concluded that the SmDyFeCo thin film gives a higher magneto optic recording density and is likely to become one of the magneto optic materials for the next generation of magneto optic disk. |
