Abstract
The nuclear forward scattering (NFS) of synchrotron radiation is especially suited for probing magnetism at very high pressure, here in the Mbar range , by the nuclear resonances of Fe-57 and Eu-151. We report on high pressure (h.p.) NFS studies with the 14.4 keV transition of (5)7Fe on magnetic RFe2 Laves phases of cubic C15 structure (YFe2, GdFe2) and hexagonal C14 struct ure (ScFe2, TiFe2) at pressures up to 100 GPa (= 1 Mbar). We present also h .p. NFS studies performed with the 21.5 keV resonance of Eu-151, probing th e magnetism in the CsCl-type h.p. phase of EuTe.
