本文报道了新开发的纳米晶Fe_(69·4)Cu_(0·6)Cr_(3·2)V_(0·8)Si_(14)B_(12)合金的综合磁性能,包括直流磁性,交流有效磁导率和高频铁损。考查了新合金的起始磁化率的温度关系。观察表明退火样品在较低温度范围内不出现Hopkinson峰,用Thomas理论解释了这种现象。
This paper reports the comprehensive magnetic properties of the newly developed Fe_ (69.4) Cu_ (0.6) Cr_ (3.2) V_ (0.8) Si_ (14) B_ (12) alloy including DC magnetism, Exchange effective permeability and high frequency iron loss. The temperature dependence of the initial susceptibility of the new alloy was examined. The observation shows that the Hopkinson peak does not appear in the annealed sample at a lower temperature range, which is explained by the Thomas theory.
