Structure of Charge Density Waves in LaBaCuO
J. Sears, Y. Shen, M. J. Krogstad +8
Although charge-density wave (CDW) correlations exist in several families of cuprate supercon-ductors, they exhibit substantial variation in CDW wavevector and correlation length,…
Role of Oxygen States in the Low Valence Nickelate LaNiO
Y. Shen, J. Sears, G. Fabbris +13
The discovery of superconductivity in square-planar low valence nickelates has ignited a vigorous debate regarding their essential electronic properties: Do these materials have ap…
Strong Superexchange in a Nickelate Revealed by Resonant Inelastic X-Ray Scattering
J. Q. Lin, P. Villar Arribi, G. Fabbris +20
The discovery of superconductivity in a nickelate has inspired disparate theoretical perspectives regarding the essential physics of this class of materials. A key issue…
High-Temperature Charge-Stripe Correlations in LaEuSrCuO
Qisi Wang, M. Horio, K. von Arx +24
We use resonant inelastic x-ray scattering to investigate charge-stripe correlations in LaEuSrCuO. By differentiating elastic from inelastic scatter…
Suppression of the critical temperature of superconducting NdFeAs(OF) single crystals by Kondo-like defect sites induced by alpha-particle irradiation
C. Tarantini, M. Putti, A. Gurevich +8
We report a comprehensive investigation of the suppression of the critical temperature Tc of NdFeAs(OF) single crystal by alpha-particle irradiation. Our data indicate that irradia…
Effect of oxygen incorporation on normal and superconducting properties of MgB2 films
R. K. Singh, Y. Shen, R. Gandikota +3
Oxygen was systematically incorporated in MBE grown MgB2 films using in-situ post-growth anneals in an oxygen environment. Connectivity analysis in combination with measurements of…
Effect of stoichiometry on oxygen incorporation in MgB2 thin films
R K Singh, Y Shen, R Gandikota +2
The amount of oxygen incorporated into MgB2 thin films upon exposure to atmospheric gasses is found to depend strongly on the material's stoichiometry. Rutherford backscattering sp…
Effect of Rb and Cs-doping on superconducting properties of MgB2 thin films
R K Singh, Y Shen, R Gandikota +4
Our Rutherford backscattering spectrometry (RBS) study has found that concentrations up to 7 atomic percent of Rb and Cs can be introduced to a depth of ~700 A in MgB2 thin films b…
