The object of this proposal is to measure the partial vibrational density of states (VDOS) within the incoherent approximation for the archetypal 'strong' network forming glass... -
Inelastic Neutron Scattering study on new tetragonal compound Ce2PdGe3
Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional... -
Spin excitations in frustrated rare-earth tripod Kagome magnets
Exotic ordering phenomena resulting from magnetic frustration continue to attract attention as newtypes of frustrated compounds emerge. A very recent development in this field... -
