J. Ding et al., MOSSBAUER AND MAGNETIC STUDY OF MELT-SPUN ND4.5B18.5FE77 RIBBONS, Journal of magnetism and magnetic materials, 144, 1995, pp. 1071-1072
Remanence enhanced Nd4.5B18.5Fe77 ribbons were studied by magnetic mea
surements and Mossbauer spectroscopy. Some for the exchange coupling c
haracterised properties were observed in ribbons after optimum heat tr
eatment. Overheating caused decoupling, which was clearly detected in
magnetic measurements. The remanence enhancement was evident in Mossba
uer spectra.
