The magnetization process in an exchange-coupled {alpha}-Fe+Nd{sub 2}Fe{sub 14}B nanocomposite has been studied by M{umlt o}ssbauer spectroscopy. Measurements in fields of up to 2 T confirm that the magnetization of the soft phase is strongly coupled to that of the hard phase. Analysis of magnetization curves and magic-angle spectra of saturated samples shows that the remanence is dominated by the hard phase. {copyright} {ital 1997 American Institute of Physics.}
