Abstract

The extraordinary Heusler compound YbPd(Formula presented.)Sn is a near-full magnetic moment Yb(Formula presented.) paramagnet at high temperature, becomes superconducting below (Formula presented.)K, and orders long-range antiferromagnetic at (Formula presented.)K. (Formula presented.) is of re-entrant nature for fields between (Formula presented.) and (Formula presented.)T. The (Formula presented.) superconductivity is quenched in a field of (Formula presented.)T, whereas the field suppression of (Formula presented.) requires upward of (Formula presented.)T. This presents the possibility to study the stability of magnetic order and its (Formula presented.) behavior in the normal region of phase space. In this work, we are concerned with critical effects accompanying the suppression of magnetic order in YbPd(Formula presented.)Sn as a local-moment antiferromagnet, and we formulate a description of the specific heat of YbPd(Formula presented.)Sn in terms of field-driven quantum criticality.
