Crystal Symmetry of Stripe Ordered La1.88Sr0.12CuO4

Ruggero Frison, Julia Kuespert, Qisi Wang +12

We present a combined x-ray and neutron diffraction study of the stripe ordered superconductor \lscox{0.12}. The average crystal structure is consistent with the orthorhombic $Bmab…

Polytypism and Superconductivity in the NbS System

Catherine Witteveen, Karolina Gornicka, Johan Chang +3

We report on the phase formation and the superconducting properties in the NbS system. Specifically, we have performed a series of standardized solid-state syntheses in this sy…

High magnetic field ultrasound study of spin freezing in LaSrCuO

M. Frachet, S. Benhabib, I. Vinograd +11

High- cuprate superconductors host spin, charge and lattice instabilities. In particular, in the antiferromagnetic glass phase, over a large doping range, lanthanum bas…

Multiple- to single-gap superconductivity crossover in NbIrPtO alloys

Y. Xu, S. Jöhr, L. Das +5

By using mostly the muon-spin rotation/relaxation (SR) technique, we investigate the superconductivity (SC) of NbIrPtO ( and 1.6) alloys, with $T_c = 10.5…

Hidden magnetism at the pseudogap critical point of a high temperature superconductor

Mehdi Frachet, Igor Vinograd, Rui Zhou +17

The mysterious pseudogap phase of cuprate superconductors ends at a critical hole doping level p* but the nature of the ground state below p* is still debated. Here, we show that t…

Spatially Inhomogeneous Competition between Superconductivity and the Charge Density Wave in YBaCuO

J. Choi, O. Ivashko, E. Blackburn +13

The charge density wave in the high-temperature superconductor YBaCuO (YBCO) is now known to have two different ordering tendencies differentiated by their -axis…
