Pseudogap phase of cuprate superconductors confined by Fermi surface topology

N. Doiron-Leyraud, O. Cyr-Choinière, S. Badoux +15

The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which…

Spin susceptibility of charge ordered YBa2Cu3Oy across the upper critical field

R. Zhou, M. Hirata, T. Wu +9

The value of the upper critical field Hc2, a fundamental characteristic of the superconducting state, has been subject to strong controversy in high-Tc copper-oxides. Since the iss…

Fermi surface with Dirac fermions in CaFeAsF determined via quantum oscillation measurements

Taichi Terashima, Hishiro T. Hirose, David Graf +6

Despite the fact that 1111-type iron arsenides hold the record transition temperature of iron-based superconductors, their electronic structures have not been studied much because…

Selective mass enhancement close to the quantum critical point in BaFe(AsP)

V. Grinenko, K. Iida, F. Kurth +16

A quantum critical point (QCP) is currently being conjectured for the BaFe(AsP) system at the critical value 0.3. In the proximity of a QCP,…

Anisotropy of the Seebeck Coefficient in the Cuprate Superconductor YBaCuO: Fermi-Surface Reconstruction by Bidirectional Charge Order

O. Cyr-Choinière, S. Badoux, G. Grissonnanche +11

The Seebeck coefficient of the cuprate YBaCuO was measured in magnetic fields large enough to suppress superconductivity, at hole dopings and $p =…

Subsurface bending and reorientation of tilted vortex lattices in the bulk due to Coulomb-like repulsion at the surface

E. Herrera, I. Guillamon, J. A. Galvis +6

We study vortex lattices (VLs) in superconducting weak-pinning platelet-like crystals of -BiPd in tilted fields with a Scanning Tunneling Microscope. We show that vortices…

Spin excitations and the Fermi surface of superconducting FeS

Haoran Man, Jiangang Guo, Rui Zhang +17

High-temperature superconductivity occurs near antiferromagnetic instabilities and nematic state. Debate remains on the origin of nematic order in FeSe and its relation with superc…

High-field transport properties of a P-doped BaFe2As2 film on technical substrate

Kazumasa Iida, Hikaru Sato, Chiara Tarantini +5

High temperature (high-Tc) superconductors like cuprates have superior critical current properties in magnetic fields over other superconductors. However, superconducting wires for…

Superconducting properties of Ba(Fe1-xNix)2As2 thin films in high magnetic fields

Stefan Richter, Fritz Kurth, Kazumasa Iida +9

We report on electrical transport properties of epitaxial Ba(Fe1-xNix)2As2 thin films grown by pulsed laser deposition in static magnetic fields up to 35 T. The thin film shows a c…
