Sixfold enhancement of superconductivity in a tunable electronic nematic system
Chris Eckberg, Daniel J. Campbell, Tristin Metz +10
The electronic nematic phase, wherein electronic degrees of freedom lower the crystal rotational symmetry, is a common motif across a number of high-temperature superconductors. Ho…
Influence of growth flux solvent on anneal-tuning of ground states in CaFe2As2
Connor Roncaioli, Tyler Drye, Shanta Saha +1
The effects of anneal-tuning of single-crystalline samples of CaFeAs synthesized via a molten Sn flux method are investigated using x-ray diffraction, chemical composition,…
Role of electron-electron interactions in the charge dynamics of rare-earth-doped CaFe2As2
Zhen Xing, T. J. Huffman, Peng Xu +8
We have investigated the charge dynamics and the nature of many-body interactions in La- and Pr- doped CaFe2As2. From the infrared part of the optical conductivity, we discover tha…
Spin-state transition in the Fe-pnictides
H. Gretarsson, S. R. Saha, T. Drye +7
We report a Fe Kβx-ray emission spectroscopy study of local magnetic moments in the rare-earth doped iron pnictide Ca_{1-x}RE_xFe_2As_2 (RE=La, Pr, and Nd). In all samples studied…
Quenched Fe Moment in the Collapsed Tetragonal Phase of CaPrFeAs
Long Ma, G. F. Ji, J. Dai +3
We report As NMR studies on single crystals of rare-earth doped iron pnictides superconductor CaPrFeAs (=0.075 and 0.15). The As spectra…

We report measurements of the pressure dependence of the superconducting transition temperature T_c in single crystal samples of the rare-earth doped superconductor CaLa$_…
Structural collapse and superconductivity in rare earth-doped CaFe2As2
S. R. Saha, N. P. Butch, T. Drye +6
Aliovalent rare earth substitution into the alkaline earth site of CaFe2As2 single-crystals is used to fine-tune structural, magnetic and electronic properties of this iron-based s…
Superconductivity and magnetism in platinum-substituted SrFe2As2 single crystals
Kevin Kirshenbaum, Shanta R. Saha, Tyler Drye +1
Single crystals of SrFe2-xPtxAs2 (0 < x < 0.36) were grown using the self flux solution method and characterized using x-ray crystallography, electrical transport, magnetic suscept…
