Description
We have carried out magnetic and Moessbauer studies of amorphous Fe80-xTm xB20 alloys (0 ≤ x ≤ 16). With an increasing Tm content, both the Curie temperature T C and the magnetic moment of Fe atom μ Fe decrease. We have extracted the value of exchange constant A from T C and that of the local magnetic anisotropy constant K L from the coercivity. Moessbauer studies were performed in a transmission geometry and also using the conversion electron spectroscopy. Both Moessbauer spectrometry techniques show that the average hyperfine field decreases linearly with the addition of rare-earth
