Unconventional superconductors: Iron-based diversity
Anna Böhmer, Andreas Kreyssig
Nine years ago, superconductors based on the magnetic element iron were discovered. A flurry of research activity has revealed an unprecedented diversity of chemical structures and…
Effect of biaxial strain on the phase transitions of Ca(Fe1-xCox)2As2
A. E. Böhmer, A. Sapkota, A. Kreyssig +5
We study the effect of applied strain as a physical control parameter for the phase transitions of Ca(Fe1-xCox)2As2 using resistivity, magnetization, x-ray diffraction and 57Fe Mös…
Variation of transition temperatures and residual resistivity ratio in vapor-grown FeSe
A. E. Böhmer, V. Taufour, W. E. Straszheim +2
The study of the iron-based superconductor FeSe has blossomed with the availability of high quality single crystals, obtained through flux/vapor-transport growth techniques below t…
Enhancement of Tc by point-like disorder and anisotropic gap in FeSe
S. Teknowijoyo, K. Cho, M. A. Tanatar +8
A highly anisotropic superconducting gap is found in single crystals of FeSe by studying the London penetration depth, , measured down to 50 mK in samples before and after 2.5…
Anisotropic thermodynamic and transport properties of single crystalline CaKFeAs
W. R. Meier, T. Kong, U. S. Kaluarachchi +14
Single crystalline, single phase CaKFeAs has been grown out of a high temperature, quaternary melt. Temperature dependent measurements of x-ray diffraction, anisotropic…
Strong cooperative coupling of pressure-induced magnetic order and nematicity in FeSe
K. Kothapalli, A. E. Böhmer, W. T. Jayasekara +10
A hallmark of the iron-based superconductors is the strong coupling between magnetic, structural and electronic degrees of freedom. However, a universal picture of the normal state…
