MOSSBAUER STUDIES OF MAGNETIC TEXTURE IN NANOCRYSTALLINE FE73.5CU1NB3SI13.5B9 ALLOY

Mossbauer measurements have been carried out using non-polarized absor bers in order to investigate the magnetic texture in nanocrystalline F e73.5Cu1Nb3Si13.5B9 prepared from the amorphous state by crystallizati on. The results indicate a significant variation of magnetic domains i n ribbons with the annealing temperature. Upon crystallization the com ponent of the magnetization vector oriented parallel to the long axis of ribbons increases significantly and becomes dominant. The non-field annealing-induced magnetic texture probably arises from the shape ani sotropy and intensely influences the initial magnetization process.
