Title

Kondo physics in a rare earth ion with well localized 4f electrons

AuthorsStankiewicz, Jolanta; Evangelisti, Marco
Issue Date2012
PublisherAmerican Physical Society
CitationPhysical Review Letters 108(25): 257201 (2012)
AbstractDilute Nd in simple cubic LaB 6 shows electrical resistance and specific heat features at low temperature consistent with a Kondo scale of T K 0.3K. Nd has a well-localized 4f3 J=9/2 Hund's rule configuration which is not anticipated to be Kondo coupled to the conduction electrons in LaB 6. We conjecture that the unexpected Kondo effect arises via participation of 4f quadrupolar degrees of freedom of the Nd crystal-field, ground-state quartet. © 2012 American Physical Society.
