Abstract

The single-ion Kondo effect in La1−x CexB6 (0 < x ⩽ 1) is shown to cause a pronounced positive maximum in the thermal expansion coefficient near TK, and an additional negative peak at lower temperatures. An antiferroquadrupolar ordering transition is found for x > 0.8, whereas antiferromagnetic order seems to exist for x ≳ 0.5.
