抄録

The evolution of the magnetic excitation spectrum of the heavy fermion superconductor PrOs4Sb12 was studied by inelastic neutron scattering on crossing the critical field Hc2 for superconductivity at low temperature. The peak positions in energy and the peak intensities of the modes of the triplet split by magnetic field confirm the known crystal field parameters for PrOs4Sb12 in Th symmetry. A selective broadening of the lineshape occurs on increasing the magnetic field: the linewidth of the upper mode of the triplet increases while the one of the middle mode does not.
