Cascade of Metamagnetic Transitions in Heavy Fermion CePtPb

CePtPb crystallizes into a hexagonal ZrNiAl-type structure, where the magnetic Ce-ions form a quasi-Kagome lattice. Other heavy-fermion compounds with this structure, such as CePdAl and YbAgGe, have been shown to have a complicated H-T phase diagram with multiple magnetic phases. Both CePdAl and YbAgGe show a region of strange-metallic behavior near the quantum critical point. In this talk, I will present magnetic-field dependent measurements of resistivity, heat capacity and muon spin relaxation that lead to the construction of a magnetic-field-temperature phase diagram for this compound. The constructed phase diagram and physical properties of CePtPb will be compared to CePdAl and YbAgGe.
