Ultrathin zero magnetostrictive ((Fe-Co) Cr_y)_X(Si-B)_<100-x'>(x=75-81), (Y=0.05, 0.06) amorphous ribbons were fabricated in vacuum and the following results were obtained.(1) The ribbons obtained were 3-10 mum thick and about 5 mm wide, and had good surface smoothness and dimensional uniformity.(2) Extremely low core loss beyond 100 kHz was attained by thickness reduction. The loss of 5.5 mum thick ribbons at 100 kHz and 1 MHz were 16 (mW/cc) and 1.0 (W/cc) for maximum flux density B_m=0.1 T. Moreover, in the case of 6.0 mum thick ribbon with transverse magnetic field annealing, the loss at 100 kHz and I MHz were 10 (mW/cc) and 700 (mW/cc). These values were about 1/8-1/3 of those of Mn-Zn high-frequency ferrites or 5 mum Supermalloy tape wound cores.(3) Markedly high initial permeability was also obtained. The values of 6.0 mum thick ribbons with transverse field annealing at 1 MHz and 10 MHz were about 13000 and 2200 for a driving field H_m=2 mOe, respectively.(4) The domain patterns of some ultrathin ribbons were observed by the Kerr effect. The effect of transverse magnetic field annealing on the magnetic properties was also studied and their relation to the soft magnetic properties was discussed.

超淡片磁磁性（（fe-co）cr_y）_x（si-b）_ <100-x'>（x = 75-81），（y = 0.05，0.06）在真空中制造了无形色带，获得了以下结果，并获得了以下结果。均匀性。（2）通过厚度减小，极低的核心损失超过100 kHz。在100 kHz和1 MHz时损失5.5 MUM厚的丝带，最大通量密度B_M = 0.1 T. 16（MW/CC）和1.0（w/cc）的损失。这些值约为Mn-Zn高频铁素体或5个妈妈超级球形胶带伤口核的1/8-1/3。在1 MHz处进行横向电场退火的6.0 MUM厚丝带的值分别为13000和2200，对于驱动场H_M = 2 MOE。（4）Kerr效应观察到某些超薄丝带的域模式。还研究了横向磁场退火对磁性特性的影响，并讨论了它们与软磁性能的关系。
