Meissner state in highly forced superconducting systems

Abstract

We show a possible relationship between the deformation factor [Formula: see text] and the inverse of the de Gennes parameter [Formula: see text] in the Ginzburg–Landau model for a superconducting meso-film and meso-disk in the presence of an external magnetic field in the Meissner state. It is shown that there is a lineal relationship between [Formula: see text] and [Formula: see text] when a forced model is considered. This being the case, the curves for the magnetization M (H) and the magnetic susceptibility [Formula: see text] are presented for several values of [Formula: see text] and [Formula: see text], showing an acceptable qualitative fit between these curves.

Vortex state in a superconducting mesoscopic irregular octagon

“…( 5) does not exist, leaving only a superconducting condensate ψ 1 . For the computational mesh we use ∆x = ∆y = 0.1 [13,15,16,32]. In the field cooling processes simulations for we take T = 0.1.…”

“…This field has developed since its discovery in 1908 by H. Onnes, G. Holts and J. Flint [6], encompassing different branches that they contemplate, mesoscopic superconductivity [7,8], topological [9][10][11], multi-band [12,13], frustrated superconductivity [14] and its applications in electronic devices reaffirm its importance in the advancement of new technologies based on vortex control [15,16], Magnons [17] or Hopfios [18], not without first mentioning the discovery of superconductivity in ferromagnetic systems [19]. In general, until now, there are three specific theoretical models for to study the superconducting state.…”
