Analytic theories for magnetic skyrmions

Skyrmions are tiny swirls in the local magnetization that can exist in thin films at room temperatures. They were only imaged for the first time in 2009 and are promising candidates for high-density and low-energy data storage. A key to their existence is an asymmetric magnetic exchange interaction known as the “Dzyaloshinskii-Moriya interaction” (DMI). In this talk, I will discuss our analytic models for predicting the size of skyrmions. These analytic tools provide scientists and engineers with an easy way to make predictions about new magnetic materials for data storage applications.
