Abstract
Microstructure and magnetic properties of Fe89Zr7B4 nanocrystalline ma terial have been studied in the temperature range 4.2-550 K. It has be en shown that conventional magnetization measurements and Mossbauer sp ectroscopy give consistent results on the volumetric fraction of the c onstituent phases. In the Mossbauer spectra, besides of the contributi ons from bcc-Fe crystalline phase and that of the residual amorphous m atrix? an additional component was observed and attributed to the crys talline grain-amorphous matrix interfaces. Magnetic behavior of the in terfacial layer and its changes with temperature are also discussed. ( C) 1997 Elsevier Science S.A.
