SEMINAR ON “MAGNETISM”

During the course of this seminar we had 4 presentations by people who had participated in the earlier poster session. The speakers and titles were:

(1) U. Gasser (PSI, Switzerland): “Dimer splitting in R_xY_1−xNi₂B₂C”. High resolution inelastic work done on polycrystalline samples at the IRIS spectrometer at ISIS and determining the exchange interactions in these superconducting materials.

(2) B. Roessli (PSI, Switzerland): “Enhancement of magnetic fluctuations in UPd₂Al₃ below T_c”. High resolution work done on single crystals at the cold source IN14 triple axis spectrometer at the ILL and also involving polarisation analysis.

(3) P. Wisniewski (Wroclaw, Poland): “Magnetic structures in U₃X₄-type uranium pnictides - neutron diffraction studies”. Elastic scattering experiments done at Saclay on single crystals with both polarised and unpolarised neutrons.

(4) A. Schneidewind (TU Dresden): “Investigation of magnetic structures of NdCu₂ by synchrotron x-ray scattering". Work done at the ID20 diffractometer at the ESRF and involving resonant and non-resonant scattering, as well as polarisation analysis…
