Magnetic and magneto-optical properties of amorphous A1−xFex alloys (A = B, Ge, and Sn)

Abstract
Amorphous alloys of the type A1−xFex, where A represents B, Ge, or Sn, were prepared by two‐source coevaporation in the ranges 0.3⩽x⩽0.9, 0.30⩽x⩽0.65, and 0.45⩽x⩽0.64. The magneto‐optical properties of these alloys were examined by means of the polar Kerr effect. The magnetic properties of the alloys with B and Ge were also studied. The concentration dependence of the Fe moments in the Fe metalloid alloys is analyzed in terms of a model in which due account is taken of the fact that the variation of the heat of alloying in the various iron metalloid alloys entails a variable degree of intrinsic compositional short‐range order.
