Magnetic properties and Mossbauer studies of FesGZr7B6Cul alloy

Abstract: Thc microstructure. magnetic susccptibilily and its disaccomrnodation for the amorphous and partially crystallized Fc~,2r,B~Cu, ribbons arc investigated. Duc to thc stress relief. the dccrcase of the Curie ternperaturc aftcr the annealing of thc sample at 573 K is obsen~cd. Morcovcr, this treatment lcads to thc decrease of the averagc hypcrfinc field. The sample containing 7 % of a-Fc phase czhibits a superparamagnetic bchaviour. The d~saccommodation of the magnetic susccplibilih in partially crl\stalli~ed ribbons is ~ 0 ~ e c t e d with the relaxation processes occurring in the amorphous matrix. 1
