Interface control by homoepitaxial growth in pulsed laser deposited iron chalcogenide thin ilms

Sebastian Molatta, Silvia Haindl, Sascha Trommler +3

Thin film growth of iron chalcogenides by pulsed laser deposition (PLD) is still a delicate issue in terms of simultaneous control of stoichiometry, texture, substrate/film interfa…

Coexistence of superconductivity and itinerant ferromagnetism in Sr0.5Ce0.5FBiS2-xSex (x = 0.5 and 1.0), the first non-U material with Tc < TFM

Gohil S. Thakur, G. Fuchs, K. Nenkov +4

We have carried out detailed magnetic and transport studies of the new Sr0.5Ce0.5FBiS2-xSex (x = 0.5, 1) superconductors derived by doping Se in Sr0.5Ce0.5FBiS2. Se-doping produces…

Branching of the vortex nucleation period in superconductor Nb microtubes due to inhomogeneous transport current

R. O. Rezaev, E. A. Levchenko, V. M. Fomin

An inhomogeneous transport current, which is introduced through multiple electrodes in an open Nb microtube, is shown to lead to a controllable branching of the vortex nucleation p…

Tracing the -symmetry in iron pnictides by controlled disorder

Micha Benjamin Schilling, Andreas Baumgartner, Boris Gorshunov +8

Consecutive proton irradiation of iron pnictides reduces the superconducting transition temperature to decrease monotonically. Our systematic optical THz investigations of Ba(Fe$_{…

Analysis of nonlinear conductivity of point contacts on the base of FeSe in the normal and superconducting state

Yu. G. Naidyuk, N. V. Gamayunova, O. E. Kvitnitskaya +3

Nonlinear conductivity of point contacts (PCs) on the base of FeSe single crystals has been investigated. Measured dV/dI dependencies demonstrate the prevailing contribution to the…

Solitonic spin-liquid state due to the violation of the Lifshitz condition in FeTe

Ph. Materne, C. Koz, U. K. Rößler +6

A combination of phenomenological analysis and Mössbauer spectroscopy experiments on the tetragonal FeTe system indicates that the magnetic ordering transition in compounds…
