Abstract
Micromagnetic simulation has become a useful tool to design magnetic materials and devices. In this talk I will give a short overview about micromagnetic simulation techniques and their applications. In particular I will discuss micromagnetics for magnetic recording applications and the numerical methods for computing the magnetostatic interactions between moving magnetic parts such as the write head and the magnetic recording medium. I will show how a micromagnetic solver can be combined with global minimization techniques for the optimization of the pole tip geometry in single pole write heads for high density recording. Other examples will cover spin torque oscillators and advanced materials simulations for low rare-earth high performance permanent magnets.
