Electron-phonon coupling and superconductivity-induced distortion of the phonon lineshape in VSi
A. Sauer, D. A. Zocco, A. H. Said +3
Phonon measurements in the A15-type superconductors were complicated in the past because of the unavailability of large single crystals for inelastic neutron scattering, e.g., in t…
Evolution of quasiparticle excitations with critical mass enhancement in superconducting AFe2As2 (A = K, Rb, and Cs)
Y. Mizukami, Y. Kawamoto, Y. Shimoyama +8
In the heavily hole-doped iron-based superconductors FeAs ( K, Rb, and Cs), the electron effective mass increases rapidly with alkali-ion radius. To study how the ma…
Quantum criticality in AFe2As2 with A = K, Rb, and Cs suppresses superconductivity
Felix Eilers, Kai Grube, Diego A. Zocco +10
Superconductors close to quantum phase transitions often exhibit a simultaneous increase of electronic correlations and superconducting transition temperatures. Typical examples ar…
Lattice dynamical properties of superconducting SrPtP studied via inelastic x-ray scattering and density functional perturbation theory
D. A. Zocco, S. Krannich, R. Heid +5
We present a study of the lattice dynamical properties of superconducting SrPtP ( K) via high-resolution inelastic x-ray scattering (IXS) and ab initio calculations.…
Pressure dependence of the charge-density-wave and superconducting states in GdTe, TbTe and DyTe
D. A. Zocco, J. J. Hamlin, K. Grube +4
We present electrical resistivity and ac-susceptibility measurements of GdTe, TbTe and DyTe performed under pressure. An upper charge-density-wave (CDW) is suppressed a…

The upper critical field Hc2(T) of the multiband superconductor KFe2As2 has been studied via low-temperature thermal expansion and magnetostriction measurements. We present compell…
High pressure transport studies of the LiFeAs analogues CuFeTe2 and Fe2As
Diego A. Zocco, Duygu Y. Tütün, James J. Hamlin +4
We have synthesized two iron-pnictide/chalcogenide materials, CuFeTe2 and Fe2As, which share crystallographic features with known iron-based superconductors, and carried out high-p…
Signatures of pressure induced superconductivity in insulating Bi2212
T. Cuk, D. A. Zocco, H. Eisaki +4
We have performed several high pressure electrical resistance experiments on Bi1.98Sr2.06Y0.68Cu2O8, an insulating parent compound of the high-Tc Bi2212 family of copper oxide supe…
Superconductivity in LnFePO (Ln = La, Pr, and Nd) single crystals
R. E. Baumbach, J. J. Hamlin, L. Shu +3
Single crystals of the compounds LaFePO, PrFePO, and NdFePO have been prepared by means of a flux growth technique and studied by electrical resistivity, magnetic susceptibility an…
Pressure induced superconductivity in the charge density wave compound TbTe3
