摘要: Abstract Spin resonance measurements have been used to obtain the temperature dependence of magnetization in (FexNi1−x)75P16B6Al3 alloys for 4 ≲ T 300K. With x = 0.5, spin wave theory is adequate account observations. For 0.4 and 0.3 marked deviations from 3 2 behavior are noted below ∼ 70K we propose a simple model these deviations.
