Abstract :
Amorphous alloys of composition Fe86Zr7Cu 1B6 are prepared and annealed in the temperature range from 570 to 950 K, obtaining several degrees of nanocrystallization. Magnetic and Mossbauer measurements show the different phases that appear in the samples after the heating, and their percentage, depending on the annealing temperature. The Curie temperature of the amorphous phase is shown to remain almost unchanged during the crystallization. Mossbauer spectroscopy reveals subtle changes in the structure
