Abstract

The annealing effect on the magnetic phase diagram of the Y-Fe amorphous alloy system has been investigated by means of differential magnetic susceptibility. Y-Fe amorphous alloys annealed at 250 degrees C for 30 min exhibit a re-entrant spin-glass behaviour in a similar manner to the as-prepared samples in an applied magnetic field. The Curie temperature is enhanced but the spin-freezing temperature Tf is depressed by annealing. These facts suggest that the Fe-Fe interatomic distance, which significantly influences the magnetic properties, increases on annealing. The magnetic phase diagram of the Y-Fe amorphous alloy system in an applied magnetic field is similar to that of various re-entrant spin-glass-type Fe-based amorphous alloy systems in zero magnetic field.
