Abstract:Ce 2 Pd 2 In (Mo 2 FeB 2 -type of crystal structure) with the ferromagnetic ground state based on Ce-4 f 1 states exhibits two distinct phases of pressure-driven destruction of magnetic order. For pressures up to 3 GPa, a gradual buildup of Kondo interactions and of incommensurate spin-density wave are observed, while the ordering temperature remain in the range 4-5 K. A gradual but fast suppression of magnetism and formation of heavy fermion state (estimated Sommerfeld coefficient γ exceeding 400 mJ mol −1 K … Show more
