Structure and phase analysis of electrochemically synthesized Fe–W

Structural and magnetic study of electrochemically synthesized Fe91.2W8.8 amorphous powder was realized. Mossbauer spectrum of the as prepared material with its paramagnetic and magnetic part includes gamma-Fe plus components of Fe-W solid solution overlapped by amorphous magnetic and paramagnetic phases, stable almost down to 20 K. After thermomagnetic curve measurement, the increase in the intensity of the magnetic part was observed. Phases resulting from thermal decomposition agree with those in the equilibrium Fe-W phase diagram. (C) 2003 Elsevier B.V. All rights reserved.
