Outline of Final Research Achievements

Crystalline electric field (CEF) ground state of SmOs_4Sb_12, which shows magnetic field robust heavy fermion state, is determined as Gamma_67 by ultrasonic measurements under pulsed-magnetic field. Further, the results of ultrasonic measurements under hydrostatic pressure on this compound strongly suggests that a magnetic octupolar interaction plays an important role in the low-temperature magnetic ordered phase in SmOs_4Sb_12.
On the other hand, the elastic constant (C_11-C_12)/2 of a new cage-structural compound PrNi_2Cd_20, which was grown at Maple group in University of California San Diego, is observed down to 30 mK. It is clarified that this system has Gamma_3 non-Kramers doublet CEF ground state.
