Quantum critical point in ferromagnetic Kondo lattice CePt at high pressure

Abstract We report on measurements of the (AC) magnetic susceptibility and the electrical resistance of the ferromagnetic compound CePt under pressures up to ∼14 GPa. The Curie temperature T C is found to decrease rapidly beyond 11 GPa approaching a quantum critical point (QCP) between 11 and 12 GPa. Close to that QCP the resistance depends linearly on the temperature over two decades indicating non-Fermi liquid (NFL) behaviour. At higher pressures a T 2 power law starts to develop as a hallmark of Fermi liquid (FL) behaviour.
