Abstract

The specific heat C _p of metallic SrB ₆ single crystals shows an anomalous behavior for T ∼ 5 K which varies strongly with an applied magnetic field. This is consistent with a two-level Schottky system. We ascribe the excess of C _p in this temperature range to localized magnetic moments. In addition, features that are attributable to a partial ferromagnetic polarization of a conduction electron gas are observed. These results are supported by magnetization measurements and are compatible with the transport properties reported previously (Stankiewicz 2016 Phys. Rev. B 94 125141).
