説明
We propose a theory of the field-induced ordered state in PrOs4Sb12. It is based on an antiferro-quadrupolar (AFQ) interaction in the low-lying singlet–triplet subspace. Using a pseudo-spin description, we clarify a hidden symmetry in the local Hamiltonian and its relation with possible order parameters. Stable AFQ phases are determined for the direction of magnetic fields, and the effect of Th symmetry on the anisotropic phase diagram is discussed.
