Target for magneto-optical recording media and method for producing same

摘要

A target for magneto-optical recording media having a microstructure having a matrix phase of a eutectic structure of a rare earth metal and an iron-group metal, particles I made of a pure iron-group metal or an alloy thereof and having an average diameter of 200 mu m or less and particles II made of a corrosion resistance-improving metal and an iron-group metal and having an average diameter of 200 mu m or less is produced by mixing rapidly-quenched powder A made of the rare earth metal and the iron-group metal and having a eutectic structure with powder B made of a pure iron-group metal or an alloy thereof and having an average diameter of 200 mu m or less, and powder C made of the corrosion resistance-improving metal and the iron-group metal and having an average diameter of 200 mu m or less, and pressure-sintering the resulting mixed powder at a temperature lower than a liquid phase-appearing temperature.
