Finite-Temperature Micromagnetics of Hysterisis for Misaligned Single Iron Nanopillars

TL;DR

This paper investigates the hysteresis behavior of misaligned single iron nanopillars using micromagnetic simulations, comparing results from simplified models and full simulations to the classical Stoner-Wohlfarth model.

Contribution

It introduces detailed micromagnetic analysis of misaligned nanopillars and compares these results with traditional models, providing new insights into their magnetic behavior.

Findings

Micromagnetic simulations reveal complex hysteresis in misaligned nanopillars.

Comparison shows deviations from the Stoner-Wohlfarth model.

Full simulations capture effects not seen in simplified models.

Abstract

We present micromagnetic results for the hysterisis of a single magnetic nanopillar which is misaligned with respect to the applied magnetic field. We provide results for both a one dimensional stack of magnetic rotors and of full micromagnetic simulations. The results are compared to the Stoner-Wohlfarth model.
