Em. Baggio-saitovitch et al., Magnetism in strongly correlated electron systems as seen by Fe-57 Mossbauer probe, HYPER INTER, 126(1-4), 2000, pp. 263-268
Fe-57 Mossbauer spectroscopy has been used to study rare earth intermetalli
c compounds having strongly correlated electronic properties, where the tra
nsition metal carries no magnetic moment. In this case Fe-57 is a local pro
be to detect very small transferred hyperfine fields (B-thf) from the rare
earth sites.
