## Abstract

The $Fe_{73.5}Cu_{1}Nb_{3}Si_{13.5}B_{9}$ FINEMET alloy has been prepared by the rapid solidification technique. The critical behaviour of this alloy in the amorphous as well as in its nanocrystalline states has been studied near their respective Curie temperatures. From the values of the critical exponents one can conclude that the alloy behaves like a 3D Heisenberg ferromagnet in the amorphous and nanocrystalline states. But there exists a slight increase in the value of \beta for the alloy annealed at 823 K (the nanocrystalline state) as observed in most of the amorphous alloys.
