Quadrupolar Susceptibility and Magnetic Phase Diagram of PrNiCd with Non-Kramers Doublet Ground State
In this study, ultrasonic measurements were performed on a single crystal of
cubic PrNiCd, down to a temperature of 0.02 K, to investigate the
crystalline electric field ground state and search for possible phase
transitions at low temperatures. The elastic constant ,
which is related to the -symmetry quadrupolar response, exhibits the
Curie-type softening at temperatures below 30 K, which indicates that the
present system has a non-Kramers doublet ground state. A
leveling-off of the elastic response appears below 0.1 K toward the
lowest temperatures, which implies the presence of level splitting owing to a
long-range order in a finite-volume fraction associated with
-symmetry multipoles. A magnetic field-temperature phase diagram of
the present compound is constructed up to 28 T for [110]. A clear
acoustic de Haas-van Alphen signal and a possible magnetic-field-induced phase
transition at 26 T are also detected by high-magnetic-field
measurements.Comment: 13 pages, 7 figure
