抄録

We have investigated the physical properties of Ce_0.7Pr_0.3B₆ in order to clarify the doping effect on the multipolar interactions in CeB₆ and PrB₆. As a result of the suppression of the antiferro-quadrupolar ordering temperature T_Q and the enhancement of T_N by Pr doping, six long-range ordered (LRO) phases appear. T_Q exhibits a smooth increase with increasing magnetic field as in CeB₆. At a high magnetic field, above ∼10 T, only phase II exists. As for the three LRO phases below ∼10 T and below T_Q, there exists a possibility of incommensurate quadrupolar and magnetic ordering. A new question of how the quadrupolar ordering is compatible with the magnetic ordering appears in the present study. The coexistence of the magnetic and quadrupolar orderings in Ce_0.7Pr_0.3B₆ indicates that the strong Ce–Pr interaction is different from the weak Ce–Nd interaction in Ce_xNd_1−xB₆.
