 Abstract: CePt3SiCePt3Si is a novel ternary compound exhibiting antiferromagnetic order at View the MathML sourceTN≈2.2K and superconductivity (SC) at View the MathML sourceTc≈0.75K. Large values of View the MathML sourceHc2′≈-8.5T/K and View the MathML sourceHc2(0)≈5T indicate Cooper pairs formed out of heavy quasiparticles. The mass enhancement originates from Kondo interaction with a characteristic temperature View the MathML sourceTK≈8K. NMR and μSRμSR measurements evidence coexistence of SC and long-range magnetic order on a microscopic scale. Moreover, CePt3SiCePt3Si is the first heavy fermion SC without an inversion symmetry. This gives rise to a novel type of NMR relaxation rate 1/T11/T1 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.
