High-pressure mossbauer studies of magnetism in RFe2 laves phases and Eu-chalcogenides

A review is given on current high-pressure studies of magnetism employing t he new method of nuclear forward scattering of synchrotron radiation as wel l as the conventional Mossbauer effect. Comparative studies of the magnetic properties of intermetallic RFe2 Laves phases and Eu(II)-chalcogenides are described. We present as examples the pressure induced changes in YFe2 and ScFe2 at pressures up to 100 GPa as well as studies of EuTe in the NaCl-ty pe and the CsCl-type high-pressure phase. Future high-pressure applications of nuclear resonant scattering will be discussed.
