| abstract | We report on synthesis, crystal structure, magnetic, thermodynamic, and transport properties of the compound YbPd 2 In , crystallizing as a Heusler structure type. A trivalent state of the rare earth was determined by fitting the magnetic susceptibility with a Curie-Weiss law. This compound is characterized by showing very weak magnetic interactions and a negligible Kondo effect. A specific-heat jump was observed at T ≈ 250 mK , followed at higher temperature by a power-law decrease of C P ( T ) / T . The resulting large electronic entropy increase at very low temperature is rapidly shifted to higher temperature by the application of magnetic field. This magnetocaloric effect places YbPd 2 In as a very good candidate for adiabatic demagnetization cooling processes. |
