Thick Permalloy films for the imaging of spin texture dynamics in perpendicularly magnetized systems

TL;DR

This paper demonstrates that thick Permalloy films with weak perpendicular magnetic anisotropy are effective for studying spin texture dynamics, including skyrmions and complex spin configurations, in magnetized systems.

Contribution

It introduces thick Permalloy films as a new test system for investigating gyration dynamics in various magnetic states, both trivial and non-trivial.

Findings

Permalloy films exhibit weak growth-induced perpendicular magnetic anisotropy.

Thick Permalloy films are suitable for studying topologically trivial and non-trivial spin textures.

The films enable investigation of spin dynamics from isolated skyrmions to complex nπ configurations.

Abstract

We demonstrated that thick Permalloy films exhibiting a weak growth-induced perpendicular magnetic anisotropy can be employed as an ideal test system for the investigation of gyration dynamics in topologically trivial and non-trivial magnetic states ranging from an isolated magnetic skyrmion to more complex n$\pi$ spin configurations.
