Abstract

Local magnetic interactions and spin configurations in α-Fe/Nd2Fe14B composite exchange-spring magnets have been investigated by Mössbauer spectroscopy and the magnetic behaviour was analysed by magnetometry. A new method for the evaluation of the coupling strength between soft and hard magnetic phases is proposed.
