Magnetic Field Inversion in Vortices in Multilayers

TL;DR

This paper investigates dense vortex lattices in highly anisotropic multilayers under high magnetic fields, revealing that magnetic field inversion can occur away from vortex centers when layers are sufficiently spaced.

Contribution

It introduces the phenomenon of magnetic field inversion in vortices within multilayers, a novel insight into vortex behavior in anisotropic superconducting structures.

Findings

Magnetic field inversion occurs away from vortex centers.

Inversion depends on layer spacing and anisotropy.

Dense vortex lattices exhibit unique magnetic properties.

Abstract

We present a description of very dense vortex lattices in highly anisotropic multilayers, for high fields parallel to the layers. We show that a magnetic field inversion can occur away from the center of a vortex, provided the layers are sufficiently far apart.
