Extreme instability of magnetic Fe-moment in amorphous alloys under pressure
Result description
The effect of high hydrostatic pressure on magnetization of the selected Fe-, FeNi-, FeCr- and FeW-based amorphous alloys has been studied in pressure range up to 1.2 GPa. The very strong non-linear decrease of magnetization under pressure was observed in all the studied alloys, with the extreme value of dlnM/dP =780*10(-3) GPa(-1) in the case of the amorphous Fe93Zr7 alloy. Moreover, the spin glass behaviour of the alloy at temperatures below 50 K has been strongly changed by pressure. The received results support the theoretical concepts based on a dominant role of the pressure-induced widening of the 3d-band of transition metals under high pressure.
