Inelastic neutron scattering study on 4f-electron multipole system PrTr2X20 (Tr: transition metal, X: Al and Zn)

We have conducted inelastic neutron scattering measurements to investigate the crystal-electric-field (CEF) levels associated with Pr3+4f2-electron configuration in the PrTr2X20 (Tr: transition metal, X: Al and Zn). Hybridization between conduction electrons and 4f electrons has been deduced from th...

Description
Summary:We have conducted inelastic neutron scattering measurements to investigate the crystal-electric-field (CEF) levels associated with Pr3+4f2-electron configuration in the PrTr2X20 (Tr: transition metal, X: Al and Zn). Hybridization between conduction electrons and 4f electrons has been deduced from the spectral widths, which is a key factor for understanding the anomalous low-temperature transport properties and the ordering phase transitions in the PrTr2X20. We also discuss structural-transition effects on local symmetries of the Pr-ion sites.
