Thermodynamics of type II superconductors in electromagnetic field based on the Ginzburg-
Landau theory is presented. The Abrikosov flux lattice solution is derived using an …

Vortex matter in type-II superconductors is a model complex system belonging to the vast
ensemble of disordered elastic media. In all these systems, depinning occurs when an …

We report a pronounced peak effect in the magnetization and the magnetocaloric coefficient
in a single crystal of the superconductor Nb 3 Sn. As the origin of the magnetization peak …

The range of critical thermal fluctuations in “classical” bulk superconductors is extremely
small and especially in low fields hardly experimentally accessible. With a new type of …

We study the nonlinear effects in the current-voltage characteristics of Nb superconducting
thin films, induced both by the current dependence of the pinning force and by the electric …

The temperature behavior of the first critical field (BC 1) of superconducting thin film samples
can be determined with high accuracy using an inductive and contactless method. Driving a …

Fundamental and higher harmonics of the ac magnetic susceptibility have been measured
on LaFeAsO 0.92 F 0.08 samples as a function of the temperature, at various amplitudes …

The superconducting properties of mm-sized Fe 1.02 Se crystals grown by a flux method are
investigated. The structural and morphological features are studied by x-ray diffraction …

The AC magnetic response of multi-domain FeSe crystals has been explored by means of
fundamental and third harmonic AC magnetic susceptibility (ACMS) analysis. Our previous …

Abstract We have synthesized '1144'-type (Ca1-xPrxKFe4As4 and CaKFe4As4), and '122'-
type (Ba0. 6K0. 4Fe2As2 and Ba0. 6Rb0. 4Fe2As2) iron-based superconductors. Based on …
