Description
The skutterudite superconductor PrOs4Sb12 exhibits a field-induced phase transition that is interpreted as an antiferro-quadrupolar (AFQ) ordering in the low-lying singlet-triplet crystal field levels. In this paper, we study theoretically the effect of uniaxial strains on the field-induced AFQ order using the pseudo-spin model introduced previously. It is shown that the strains stabilize the AFQ state in lower magnetic fields by relaxing the competing AFQ interaction. The characteristic evolution from the field-induced order to the zero-field one is elucidated by changing the strength of the strains
