PRESSURE EFFECTS ON THE CURIE TEMPERATURE AND ELECTRICAL RESISTANCE OF Fe-BASED AMORPHOUS ALLOYS.

The magnitude of pressure derivatives of the Curie temperature for Fe//1//0//0// minus //xZr//x and (Fe//1// minus //xM//x)//9//0-Zr//1//0 (M: Ni, Co, Cr or Mn) amorphous alloys decreases with increasing X. In most cases, a shift in the Curie temperature as a function of pressure is not linear. The electrical resistance vs. temperature curves of alloys with low X concentrations exhibit a minimum around the Curie temperature and this shifts towards a lower temperature with pressure.
