Contribution

It introduces the study of asymmetric mesoscopic superconductors and reveals their distinctive vortex configurations and magnetic responses using Ginzburg-Landau theory.

Findings

Asymmetrical vortex patterns are observed in the mesoscopic sphere.

Vortex asymmetry affects transverse magnetization and torque signals.

Long and short vortices coexist in the studied geometry.

Abstract

We show that asymmetrical mesoscopic superconductors bring new insight into vortex physics where we found the remarkable coexistence of long and short vortices. We study an asymmetrical mesoscopic sphere, that lacks one of its quadrants, and obtain its three-dimensional vortex patterns by solving the Ginzburg-Landau theory. We find that the vortex patterns are asymmetric whose effects are clearly visible and detectable in the transverse magnetization and torque.
