Temperature and doping dependence of normal state spectral properties in a two-orbital model for ferropnictides
(Elsevier Science, 2016-04)
Using a second-order perturbative Green's functions approach we determined the normal state spectral function A(k→,ω) employing a minimal model for ferropnictides. Used before to study magnetic fluctuations and superconducting ...
Effect of Ni doping on vortex pinning in CaK(F e1-x N ix)4 A s4 single crystals
(American Physical Society, 2019-08)
We study the correlation between chemical composition and vortex dynamics in Ni-doped CaK(Fe1-xNix)4As4 (x=0, 0.015, 0.025, 0.03, and 0.05) single crystals by performing measurements of the critical current densities Jc ...
Combined experimental and theoretical studies of pressure effects in La2Sb
(2017-01-01)
The 5 K superconductor La2Sb shares some structural similarities with the iron-pnictides and -chalgogenides, especially the so-called 122-compounds, despite lacking a 3d-metal component. In order to look for similarities ...
Possible Unconventional Superconductivity In Substituted Bafe 2 As 2 Revealed By Magnetic Pair-breaking Studies
(Nature Publishing Group, 2014)
Evidence of precursor orthorhombic domains well above the electronic nematic transition temperature in Sr(Fe1-xCox)2As2
(IOP Publishing, 2019-09)
Raman scattering, synchrotron x-ray diffraction, specific heat, resistivity and magnetic susceptibility measurements were performed in Sr(Fe1-xCox)2As2 [x = 0.24(3)] single crystals with superconducting critical temperature ...
Estudio de la dinámica de vórtices en superconductores a base de hierro
(2013)
Se produjeron pelíıculas delgadas superconductoras de las familias a base de hierro 122 [Fórmula Química], por el método de deposición por laser pulsado (PLD). Se estudio el efecto de la temperatura, composición y uso ...
