Abstract

We have synthesized a new intermetallic compound with a distorted Heusler structure, YbRh $_{2}$ Pb. We present a study of the magnetic, thermal, and transport properties. Heat capacity measurements revealed that YbRh $_{2}$ Pb orders magnetically below T $_{N}$ =0.57 K from a paramagnetic state with substantial crystal electric field splitting. Magnetic field further splits the ground state, which leads to the suppression of magnetic order in YbRh $_{2}$ Pb.
