Heavy fermion superconductivity and magnetic order in noncentrosymmetric CePt3Si.
نویسندگان
چکیده
CePt3Si is a novel heavy fermion superconductor, crystallizing in the CePt3B structure as a tetragonally distorted low symmetry variant of the AuCu3 structure type. CePt3Si exhibits antiferromagnetic order at T(N) approximately 2.2 K and enters into a heavy fermion superconducting state at T(c) approximately 0.75 K. Large values of H(')(c2) approximately -8.5 T/K and H(c2)(0) approximately 5 T refer to heavy quasiparticles forming Cooper pairs. Hitherto, CePt3Si is the first heavy fermion superconductor without a center of symmetry.

Non-centrosymmetric Heavy-Fermion Superconductors
In this chapter we discuss the physical properties of a particular family of non-centrosymmetric superconductors belonging to the class heavy-fermion compounds. This group includes the ferromagnet UIr and the antiferromagnets CeRhSi3,CeIrSi3,CeCoGe3,CeIrGe3 and CePt3Si, of which all but CePt3Si become superconducting only under pressure. Each of these superconductors has intriguing and interest...
متن کاملUnconventional superconductivity and magnetism in CePt3Si1−xGex
CePt3Si is a novel ternary compound exhibiting antiferromagnetic order at TN ≈ 2.2 K and superconductivity (SC) at Tc ≈ 0.75 K. Large values of H ′ c2 ≈ −8.5 T/K and Hc2(0) ≈ 5 T indicate Cooper pairs formed out of heavy quasiparticles. The mass enhancement originates from Kondo interaction with a characteristic temperature TK ≈ 8 K. NMR and μSRmeasurements evidence coexistence of SC and long r...
متن کاملAntiferromagnetic Kondo lattice compound CePt3P
A new ternary platinum phosphide CePt3P was synthesized and characterized by means of magnetic, thermodynamic and transport measurements. The compound crystallizes in an antiperovskite tetragonal structure similar to that in the canonical family of platinum-based superconductors APt3P (A = Sr, Ca, La) and closely related to the noncentrosymmetric heavy fermion superconductor CePt3Si. In contras...
متن کاملEffect of hydrostatic pressure on the ambient pressure superconductor CePt3Si
We studied the evolution of superconductivity (sc) and antiferromagnetism (afm) in the heavy fermion compound CePt3Si with hydrostatic pressure. We present a pressure-temperature phase diagram established by electrical transport measurements. Pressure shifts the superconducting transition temperature, Tc, to lower temperatures. Antiferromagnetism is suppressed at a critical pressure Pc ≈ 0.5 GPa.
متن کاملPhysical Characterization of the Heavy Fermion Superconducting Noncentrosymmetric CePt3Si System and its Variants
The CePt3Si system has recently been reported as the only heavy fermion system with a lack of inversion symmetry in the crystal structure to display superconducting properties. This discovery is in partial disagreement with the traditional Bardeen-Cooper-Schrieffer (BCS) theory of superconductors, which involves electron phonon mediated pairing. The previously published data, January 2004, repo...
