Evidence for two-gap superconductivity in the non- centrosymmetric compound LaNiC2
We study the superconducting properties of the noncentrosymmetric compound LaNiC2 by measuring the London penetration depth 1k(T ), the specific heat C(T, B) and the electrical resistivity ρ(T, B). Both 1λ(T ) and the electronic specific heat Ce(T ) exhibit behavior at low temperatures that can be described in terms of a phenomenological two-gap Bardeen–Cooper–Schrieffer (BCS) model. The residu...
متن کاملIntroduction to unconventional superconductivity in non-centrosymmetric metals
These lecture notes are an extension of my previous notes [1] presented in this lecture series and are concerned with the recently emerging research field of unconventional superconductivity in non-centrosymmetric metals. Inversion symmetry together with time reversal symmetry represent key symmetries for the formation of Cooper pairs in superconductors and allows to distinguish between even-pa...
متن کاملCentrosymmetric and pseudo-centrosymmetric structures refined as non-centrosymmetric.
The behaviour of the Flack parameter for centrosymmetric and pseudo-centrosymmetric crystal structures based on crystal structures published as being non-centrosymmetric is presented. It is confirmed for centrosymmetric structures that the value obtained for the Flack parameter is critically dependent on the Friedel coverage of the intensity data, approaching 0.5 for a coverage of 100% and stic...
متن کاملNon-centrosymmetric Na3Nb4As3O19
A new non-centrosymmetric compound, tris-odium tetra-niobium triarsenic nona-deca-oxide, Na(3)Nb(4)As(3)O(19), has been synthesized by a solid-state reaction at 1123 K. The structure consists of AsO(4) tetra-hedra and NbO(6) octa-hedra sharing corners to form a three-dimensional framework containing two types of tunnels running along the c axis, in which the sodium ions are located. Na(+) catio...
متن کاملNon-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...
