摘要(Abstract)：

研究了同一种热处理制度下不同厚度Fe_(73.7)Si_(15.3)B_7Nb_3Cu_1合金的组织结构和软磁性能。结果表明：合金优异的高频损耗性能来源于细小的晶粒尺寸和细化的磁畴，带材越薄晶粒尺寸越小，且内部磁畴结构也较细小，使用目前文献中报道的最薄(10～12μm)纳米晶带材制成的环形磁心在100 kHz、0.2 T下的损耗最小，为14.94 W/kg;磁心损耗(P_s)与最大磁通密度(B_m)符合幂律关系P_s=P_0B_m~c,带材越薄指数c值越小，说明采用超薄带制作成的环形磁心损耗随外加磁场变化趋势更小；进一步分离损耗后发现，剩余涡流损耗在总损耗中占比最大，而且随着带材变薄，剩余涡流损耗降低，在总损耗中所占比例增加，这种变化趋势直接导致薄带的总损耗较低。
