【摘要】 本文研究了由于元素W的加入,对非晶态Fe-B合金的居里温度T_C,热稳定性及电阻率温度系数α所产生的影响。指出随着W含量x的增加,居里温度T_C下降,稳定性得到提高。随着温度增高,电阻率的变化可用声子及局域自旋涨落的散射来解释。更多还原

【Abstract】 Effect of W addition on Curie temperature Tc, thermal stability and temperture coefficient of resistivity of amorphous Fe-B alloys are studied. The decrease of Tc and increase of thermal stability in amorphous （Fe1-xWx）_84.5B15.5 alloys with increasing W content are discussed. The change of the resistivity with increasing temperature can be interpreted in terms of the phonon and the local spin fluctuation scattering.更多还原
