THE CURIE TEMPERATURE RELAXATION BEHAVIOR OF METGLASES 2826 AND ( Fe_0.1Co_0.55Ni_0.35)₇₈Si₈B₁₄ UNDER HIGH PRESSURE

Relaxation behavior of the Curie temperature (TC) of two amorphous alloys Fe₄₀Ni₄₀P₁₄B₆ and ( Fe_0.1Co_0.55Ni_0.35)₇₈Si₈B₁₄ was investigated under high pressure up to 20kbar. Experimental results show that T_c relaxation process was restrained by high pressure. On the other hand, alternative treating sample at different pressures may enhance this process. Based on the expansion of local pressed region in an amorphous structure, a mechanism of relaxation under high pressure was suggested for explaining the above phenomena.
