Vertical line nodes in the superconducting gap structure of Sr2RuO4
Elena Hassinger, Patrick Bourgeois-Hope, Haruka Taniguchi +6
There is strong experimental evidence that the superconductor Sr2RuO4 has a chiral p-wave order parameter. This symmetry does not require that the associated gap has nodes, yet spe…
Expansion of the tetragonal magnetic phase with pressure in the iron-arsenide superconductor Ba{1-x}KxFe2As2
E. Hassinger, G. Gredat, F. Valade +11
In the temperature-concentration phase diagram of most iron-based superconductors, antiferromagnetic order is gradually suppressed to zero at a critical point, and a dome of superc…
Evidence for a small hole pocket in the Fermi surface of underdoped YBa2Cu3Oy
N. Doiron-Leyraud, S. Badoux, S. Rene de Cotret +13
The Fermi surface of a metal is the fundamental basis from which its properties can be understood. In underdoped cuprate superconductors, the Fermi surface undergoes a reconstructi…
Direct measurement of the upper critical field in a cuprate superconductor
G. Grissonnanche, O. Cyr-Choiniere, F. Laliberte +20
The upper critical field Hc2 is a fundamental measure of the pairing strength, yet there is no agreement on its magnitude and doping dependence in cuprate superconductors. We have…
Change of pairing symmetry in the iron-based superconductor KFe2As2
F. F. Tafti, A. Juneau-Fecteau, M. -E. Delage +7
The pairing mechanism in iron-based superconductors is the subject of ongoing debate. Proximity to an antiferromagnetic phase suggests that pairing is mediated by spin fluctuations…
Superconductivity in the noncentrosymmetric half-Heusler compound LuPtBi : A possible topological superconductor
F. F. Tafti, Takenori Fujii, A. Juneau-Fecteau +4
We report superconductivity in the ternary half-Heusler compound LuPtBi, with Tc = 1.0 K and Hc2 = 1.6 T. The crystal structure of LuPtBi lacks inversion symmetry, hence the materi…
New Phase Induced by Pressure in the Iron-Arsenide Superconductor K-Ba122
E. Hassinger, G. Gredat, F. Valade +10
The electrical resistivity rho of the iron-arsenide superconductor Ba1-xKxFe2As2 was measured in applied pressures up to 2.6 GPa for four underdoped samples, with x = 0.16, 0.18, 0…
Universal heat conduction in the iron-arsenide superconductor KFe2As2 : Evidence of a d-wave state

The thermal conductivity of the iron-arsenide superconductor KFe2As2 was measured down to 50 mK for a heat current parallel and perpendicular to the tetragonal c-axis. A residual l…

Comparing resistivity data of quasi-one dimensional superconductors (TMTSF)_2PF_6 and (TMTSF)_2ClO_4 along the least conducting c*-axis and along the high conductivity a -axis as a…
