Abstract:
We have studied magnetic and electrical properties of TbFe2 amorphous film prepared by R. F. sputtering. Saturation magnetization Ms(T) (77-800K), electrical resistivity ρ(T) (4.2-400K) and M?ssbauer spectra (18K, 400K) measurements were made. We obtained the Curie temperature (Tc~400K), temperature of the resistivity minimum (Tmin~360K) and the negative temperature coefficient of resistivity. M?ssbauer spectra at room temperature were resolved using both of the method of Hesse and that of Window. The hyperfine field distributions obtained by both methods are in good agreement. There are two distributions at H=210 kOe and H=25 kOe respectively. The first is consistent with ferromagnetism and the second is probably associated with Kondo-type resistance minimum. The M?ssbauer effect results indicate that the spin of the iron ion is also subjected to a local anisotropy field of random orientation. This result is consistent with the Harris model.
