Abstract
We present experimental results of elastic constants as a function of temperature and magnetic field for . We observe crystal-field effects for (J=(5/2) with the ground state and 76 K above. The B-T phase diagram gives the antiferromagnetic phase boundary and an additional phase boundary of unknown origin. For B>18 T and T≤0.8 K magnetoacoustic quantum oscillations are observed.
