Measurements of the pressure dependence of the Curie temperatures in ordered FePt and CoPt alloys were made in a high pressure region up to 12 GPa by using a double-stage multianvil apparatus. For both aloys TC decreased almost linearly by applying pressure with a rate of -5. 98 K/GPa for FePt and -6. 54 K/GPa for CoPt. These rates can be explained in accordance with the Heine's law if it is assumed that Tc is inversely proportional to the band-width.
