Description
Summary:The Nd ion doping effects on the multipolar interactions in CeB6 were studied. At high magnetic fields, the antiferro-quadrupolar (AFQ) phase II is not significantly affected by Nd doping. This may be because the Nd ion is in the paramagnetic state. However, with decreasing magnetic field, the Nd doping effect becomes apparent. This may be because Nd-Nd interaction dominates the long-range ordering at low magnetic fields. At low magnetic fields, just after TQ and TN coincide with each other when Nd ion is doped, new phases, namely, phases IIIA and V appear. Phase IIIA is the AF magnetic state where all types of quadrupolar interaction are small. The nature of phase V seems to change largely at x∼0.5. For x0.5, the AF magnetic state where both Ce and Nd ions contribute may be realized.
