Thermo-Magnetic Signature of a Superconducting Multi-band Square with Rough Surface

Thermo-Magnetic Signature of a Superconducting Multi-band Square with Rough Surface In the present work, we will study the effect that the surface roughness of the sample has on the magnetic and thermodynamic properties in a mesoscopic superconducting meso-square under an external magnetic field in a zero-field cooling process. We will analyze the magnetization, superconducting electronic density, free Gibbs energy, specific heat and entropy as a function of the roughness of the sample in a superconducting two-band square taking a Josephson type inter-band coupling. We show that the magnetic and thermodynamic properties depend on the roughness percentage of its surface. Our investigation was carried out by numerically solving the two-band time-dependent Ginzburg–Landau equations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Low Temperature Physics Springer Journals

Abstract

In the present work, we will study the effect that the surface roughness of the sample has on the magnetic and thermodynamic properties in a mesoscopic superconducting meso-square under an external magnetic field in a zero-field cooling process. We will analyze the magnetization, superconducting electronic density, free Gibbs energy, specific heat and entropy as a function of the roughness of the sample in a superconducting two-band square taking a Josephson type inter-band coupling. We show that the magnetic and thermodynamic properties depend on the roughness percentage of its surface. Our investigation was carried out by numerically solving the two-band time-dependent Ginzburg–Landau equations.
