Abstract
The effect of Mo and Nb addition on the magnetic properties of the Co68.25- xFe4.5Si12.25B15Mx (M = Mo, Nb), (x = 0, 1, 2, 3) amorphous wires prepared by a rotating water quenching technique was investigated. It was found that the substitution of Co by Mo or Nb improved the wire's glass-forming abili ty and thermal stability. The relative magnetic permeability also increased . The saturation magnetostriction changed its sign from nearly zero but neg ative to small positive. (C) 1999 Elsevier Science B.V. All rights reserved .
