Abstract

Ce-site substitution effects on the quadrupolar and octupolar interactions in CeB6 were investigated for CexR1-xB 6 (R = Nd, Gd) single crystals. In Ce6Nd 1-xB6 (x=0.8,0.7), new phase V appears between phase III and I. Phase V may be the antiferro(AF) magnetic state judging from the existence of the magnetic anisotropy clearly seen for x-0.7. Prom the x dependence of Tn and Tq, the Nd doping suppresses the AFQ and AFO interactions. In the case of Gd doping, quite unusual succesive transition III-II-V-I is observed for small Gd concentration. For larger Gd concentration, phase II is pushed up to higher fields and the AF magnetic state appears at low fields, which is not dominated by the AFQ ordering.
