摘要：

The magnetic properties of melt spun Fe52-xCo10+xNb8B30 (x = 0, 12, 24, 36) amorphous ribbons are presented and discussed. The Curie temperature together with the saturation magnetization exhibited a progressive decrease with increasing Co addition (from 631 to 512 K and from 1.24 to 0.53 T, respectively). On the other hand, the ac initial magnetic permeability displayed a diminishing trend with increasing Co content, from 7500 to 1500 at f = 0.5 kHz together with a relaxation frequency variation between 2 and 7 kHz. In addition, the alloys magnetostriction showed a decreasing tendency with increasing cobalt concentration. Results are interpreted on the basis of the detrimental effect of Co on the intrinsic magnetic properties of the alloy series. (C) 2009 Elsevier B.V. Ail rights reserved.
