摘要
The ternary uranium compound UCu2Sn shows a ferro-quadrupolar transition at T-Q = 16K originating from the ordering of the non-Kramers doublet Gamma(5) ground state. To investigate the magnetic field-temperature phase diagram of the ferro-quadrupolar state in UCu2Sn, we measured elastic modulus C-66 at magnetic fields of up to 14 T. We found an anisotropic field dependence of T-Q(H) in H parallel to [(1) over bar2 (1) over bar0], [0001], and [01 (1) over bar0]. We optimized the crystal electric field level scheme using C-66 under fields, magnetic susceptibility, and electronic entropy. The quadrupolar phase diagram is well reproduced by the obtained level scheme.
