Possible Heavy-Fermion Behavior in a Heusler-Type Compound YbPd2Sb

Magnetic, electrical transport and thermodynamic properties of a novel Heusler compound YbPd2Sb have been studied down to 40 mK in applied magnetic fields up to 14 T. The results hint at a heavy-particle nature of the electronic ground state, with some features characteristic of systems being close to Doniach's magnetic--nonmagnetic instability.
