The conductivity and the magnetization around Tc in optimally-doped YBaCuO revisited: quantitative analysis in terms of fluctuating superconducting pairs
R. I. Rey, C. Carballeira, J. M. Doval +7
We first present detailed measurements of the rounding behavior around the superconducting transition temperature, , of the in-plane electrical conductivity, magnetoconductivi…
Measurements of the superconducting fluctuations in optimally-doped BaFeNiAs under high magnetic fields: Probing the 3D anisotropic Ginzburg-Landau approach
R. I. Rey, A. Ramos-Álvarez, C. Carballeira +6
The superconducting fluctuations well inside the normal state of Fe-based superconductors were experimentally studied through the in-plane paraconductivity in several high-quality…
Direct measurement of the temperature dependence of the magnetic penetration depth in Ba(FeNi)As superconductors
R. I. Rey, A. Ramos-Álvarez, J. Mosqueira +6
The temperature dependence of the in-plane magnetic penetration depth of Ba(FeNi)As single crystals is determined directly from the shielding magnetic…
Critical and Gaussian conductivity fluctuations in BaFe1.9Ni0.1As2 superconductor
S. Salem-Sugui, A. D. Alvarenga, R. I. Rey +3
We study fluctuation conductivity in a single crystal of BaFeNiAs superconductor ( = 20 K) as a function of temperature and applied magnetic field. Magneto…
Angular dependence of the fluctuation magnetization vector above the superconducting transition of a highly anisotropic high-Tc cuprate
R. I. Rey, J. Mosqueira, N. Cotón +6
In highly anisotropic cuprate superconductors it is generally accepted that the reversible magnetization vector, M, is essentially perpendicular to the superconducting CuO2 layers…
New results on the anomalous precursor diamagnetism in the underdoped La1.9Sr0.1CuO4 superconductor
J. D. Dancausa, N. Cotón, J. M. Doval +5
The new results summarized here, including a brief comparison with the paraconductivity, further suggest that the anomalous precursor (above Tc) diamagnetism recently observed in t…
