Magnetic Compton scattering has been used to measure the momentum distribution of magnetic electrons in several materials. The polarization and frequency tunability of the elliptical multipole wiggler (EMW) makes it an ideal source for magnetic Compt

An energy dispersive beamline at NSLS was modified to allow magnetic circular X-ray dichroism studies. The description of the apparatus is given. The new, much more stable, arrangement is tested and compared with the previous one. The data acquistion

We report Magnetic Circular X-ray Dichroism (MCXD) measurements in Fe-Ni alloys. We used an energy dispersive beamline in our measurements. A polychromator spectrum contains self reference both in intensity and energy since all energies are measured

We measured the temperature dependence of the Magnetic Circular X-ray Dichroism (MCXD) effect at the GD L III absorption edge from 77 K up to 350 K, using an energy dispersive spectrometer. The low temperature, ferromagnetic region, MCXD spectrum con

Moessbauer studies of the ternary Chevrel phase and rare earth rhodium boride superconductors have been made. Anomalous phonon properties at the Sn site in SnMo/sub 6/S/sub 8/, SnMo/sub 6/Se/sub 8/, and La/sub 0/ /sub 98/Sn/sub 0/ /sub 02/Mo/sub 6/Se

NMR studies of /sup 95/Mo show that the enhancement of H/sub c/2 (approx.100 kG) in Eu-substituted SnMo/sub 6/S/sub 8/ arises from a negative s-band spin polarization at the Mo site. Moessbauer-effect studies of /sup 151/Eu indicate a small positive

Many strong-coupled superconductors have anomalous phonon properties. These anomalies manifest themselves as unusually soft modes, sometimes of a rather localized nature, or as anharmonic effects giving rise to hardening of certain modes at high temp

The vibrational motion of Sn in the high: critical-field superconductor SnMo$sub 6$S$sub 8$ has been studied with the $sup 119$Sn Mossbauer effect. The Mossbauer thermal shift and recoil-free fraction are found to contain large anharmonic contributio

The temperature dependence of the Moessbauer effect has been measured at /sup 119/Sn nuclei in Pd/sub 0.99/Sn/sub 0.01/. The thermal shift and recoil-free fraction have been interpreted using the neutron-determined phonon density of states and Mannhe

The electronic state of Er3+ in the ternary superconductor ErRh4B4 has been investigated using the Mossbauer effect in 166Er. The crystal field ground state is found to be a doublet, about 90 % of which is the state |Jz = ± 15/2>. The moment on the
