Magnetic field dependence of the precursor diamagnetism in La superconductors with magnetic Pr impurities
F. Soto, C. Carballeira, J. M. Doval +6
The interplay between fluctuating Cooper pairs and magnetic impurities in conventional BCS low-Tc superconductors has been studied through measurements of the magnetic field depend…
Precursor superconducting diamagnetism in YBa2Cu3O7-d with in-plane or intercalated magnetic impurities
F. Soto, N. Cotón, J. D. Dancausa +8
The magnetization around the superconducting transition was measured in YBa2Cu3O7-d with magnetic impurities in the CuO2 layers (Cu substituted by Zn or Ni) or between them (Y subs…
In-plane and transverse superconducting fluctuation diamagnetism in the presence of charge-density waves in 2H-NbSe2 single crystals
F. Soto, H. Berger, L. Cabo +4
The fluctuation-diamagnetism (FD) above the superconducting transition was measured in 2H-NbSe2 single crystals. The moderate uniaxial anisotropy of this compound, and some experim…
Electric and magnetic characterization of NbSe2 single crystals: anisotropic superconducting fluctuations above Tc
F. Soto, H. Berger, L. Cabo +5
Electric and magnetic characterization of NbSe2 single crystals is first presented in detail. Then, some preliminary measurements of the fluctuation-diamagnetism (FD) above the tra…
Breakdown by a magnetic field of the superconducting fluctuations in the normal state: A simple phenomenological explanation
Manuel V. Ramallo, Jesus Mosqueira, Carlos Carballeira +2
We first summarize our recent observations, through magnetization measurements in different low-Tc superconductors, of a rather sharp disappearance of the superconducting fluctuati…
Anomalous precursor diamagnetism at low reduced magnetic fields and the role of Tc inhomogeneities in the superconductors Pb55In45 and underdoped La1.9Sr0.1CuO4
L. Cabo, F. Soto, M. Ruibal +2
The magnetic field dependence of the magnetization was measured above the superconducting transition in a high-Tc underdoped cuprate La1.9Sr0.1CuO4 and in a low-Tc alloy (Pb55In45)…
