Abstract

A software 2D micromagnetic simulator (OOMMF - Object Oriented Micromagnetic Framework) was used to simulate magnetization curves and show the evolution of magnetic domains for a Permalloy (Ni80Fe20)-based thin film. A comparison between different Simulmag and OOMMF software solutions is made. This paper is intended to serve as a guide in the software simulation of magnetization dynamics in micrometer-sized structures with OOMMF while also reaching some essential conclusions regarding the development of sensing applications using associated magnetic effects. Simulation results are joined and confirmed by some experimental data.
