Discovery of Superconductivity in (Ba,K)SbO
Minu Kim, Graham M. McNally, Hun-Ho Kim +12
Superconducting bismuthates (Ba,K)BiO (BKBO) constitute an interesting class of superconductors in that superconductivity with a remarkably high of 30 K arises…
Phase separation and pairing fluctuations in oxide materials
A. Bill, V. Hizhnyakov, R. K. Kremer +3
We investigate the microscopic mechanism of charge instabilities and the formation of inhomogeneous states in systems with strong electron correlations. It is demonstrated that wit…
Low-Temperature Phase of the CdReO Superconductor: Ab initio Phonon Calculations and Raman Scattering
Konrad J. Kapcia, Maureen Reedyk, Mojtaba Hajialamdari +5
Using an {\it ab initio} approach, we report a phonon soft mode in the tetragonal structure described by the space group of the K superconductor CdReO$_…
Frustration-driven C4 symmetric orders in a hetero-structured iron-based superconductor
Jong Mok Ok, S. -H. Baek, C. Hoch +11
A subtle balance between competing interactions in strongly correlated systems can be easily tipped by additional interfacial interactions in a heterostructure. This often induces…
Point-contact spectroscopy in Co-doped CaFe2As2: nodal superconductivity and topological Fermi surface transition
R. S. Gonnelli, M. Tortello, D. Daghero +4
We performed point-contact Andreev reflection spectroscopy measurements in Ca(Fe_{1-x}Co_x)2As2 single crystals with effective x=0.060 +- 0.005. The spectra of ab-plane contacts sh…
Spontaneous stoichiometry change in a single crystal of (Ba1-x Kx)Fe2As2 produced by rapid heating method
P. Reuvekamp, F. S. Razavi, C. Hoch +3
To prevent the loss of K in growing single crystals of Ba1-x Kx Fe2 As2 we developed a rapid heating Sn-flux method. Large single crystals with the optimal superconducting transiti…
