【摘要】 以阻抗电桥法对非晶态(Fe_0.5Ni_0.5)_80-zCr_zP₁₄B₆（x=0,1,2,3,4,6,10）合金薄带的淬态和等温退火后样品的磁谱进行了测量。结果表明:退火后相对起始磁导宰μ_?提高了3.6～6倍,截止频率f_c下降,磁损耗μ₂的磁谱出现了共振峰。同时,等温退火处理对各样品相对起始磁导率的影响比改变Cr元素含量x要大得多。更多还原

【Abstract】 The magnetic spectra of as-prepared and isothermaly annealed sample of amorphous(Fe0.5Ni0.5)80-xCrxP14B6 alloy ribbon have been measured by impedance bridge method.From the measured results it can be seen that the relative initial permeability μ is increased by 3.6-6 times,the cut-off frequency is decreased and resonance peaks appeared in the magnetic spectra of magnetic loss.At the same time,the effect of isothermal annealed treatment on the relative initial permeability is much greater than the effect of various contents of Cr element.更多还原
