Interband electron pairing for superconductivity from the breakdown of the Born-Oppenheimer approximation
Myung-Hwan Whangbo, Shuiquan Deng, Jürgen Köhler +1
The origin of interband electron pairing responsible for enhancing superconductivity and the factors controlling its strength were examined. We show that the interband electron pai…
Transparent EuTiO3 films: a novel two-dimensional magneto-optical device for light modulation
Annette Bussmann-Holder, Krystian Roleder, Benjamin Stuhlhofer +6
The magneto-optical activity of high quality transparent thin films of insulating EuTiO3 (ETO) deposited on a thin SrTiO3 (STO) substrate with both being non-magnetic materials are…
Structure and Composition of the 200 K-Superconducting Phase of H2S under Ultrahigh Pressure: The Perovskite (SH-)(H3S+)
Elijah E. Gordon§, Ke Xu§, Hongjun Xiang +5
H2S is converted under ultrahigh pressure (> 110 GPa) to a metallic phase that becomes superconducting with a record Tc of 200 K. It has been proposed that the superconducting phas…
CuBr2-A New Multiferroic Material with High Critical Temperature
L. Zhao, T. L. Hung, C. C. Li +10
A new multiferroic material, CuBr2, is reported for the first time. CuBr2 has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric…
Electronic Structure and Lattice dynamics of NaFeAs
Shuiquan Deng, Jürgen Köhler, Arndt Simon
The similarity of the electronic structures of NaFeAs and other Fe pnictides has been demonstrated on the basis of first-principle calculations. The global double-degeneracy of ele…
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…
