Unconventional superconductivity and magnetism in $CeP t_{3} S i_{1 - x} G e_{x}$

Abstract

$CeP t_{3} Si$ is a novel ternary compound exhibiting antiferromagnetic order at $T_{N} \approx 2.2$ K and superconductivity (SC) at $T_{c} \approx 0.75$ K. Large values of $H_{c 2}^{'} \approx - 8.5$ T/K and $H_{c 2} (0) \approx 5$ T indicate Cooper pairs formed out of heavy quasiparticles. The mass enhancement originates from Kondo interaction with a characteristic temperature $T_{K} \approx 8$ K. NMR and $μ$ SR measurements evidence coexistence of SC and long range magnetic order on a microscopic scale. Moreover, $CeP t_{3} Si$ is the first heavy fermion SC without an inversion symmetry. This gives rise to a novel type of the NMR relaxation rate $1/ T_{1}$ which is very unique and never reported before for other heavy fermion superconductors. Studies of Si/Ge substitution allow us to establish a phase diagram.
