Abstract
The hyperfine magnetic fields at181Ta and57Fe in the ferromagnetic Laves intermetallic compounds (ZrxHf1−x)Fe2 (0≤x≤1) have been measured by the methods of TDPAC and Mössbauer effect, respectively, and shown to be practically independent of x at x≥0.4. An average value Bhf (Ta)=−6.52 T at 300 K was obtained for samples with x≥0.4, and −14.2 T for pure HfFe2 in the hexagonal C14 modification. For 0<x<0.4, a superposition of both field components was observed. A deviation of the temperature dependence of Bhf(Ta) in (Zr0.9 Hf0.1)Fe2 from that for Bhf (Fe) and the bulk magnetization was confirmed, studied in detail, and shown to exist for all x≥0.4. The temperature dependence of Bhf(Ta) in HfFe2 was close to that of Bhf (Fe).
