PhD: Magneto-ionic engineering of spin-torque

The project focuses on using magneto-ionic elements as a method of tuning magnetism, creating an indirect coupling between an applied voltage and the magnetic properties and allowing for reconfiguration of a device on the fly. The goal is to incorporate solid-state electrolyte sources into thin film heterostructures, creating a compact device where a voltage can be applied to an electrolyte layer to force the migration of ions into or out of an adjacent magnetic layer.

The PhD candidate will investigate how this electrochemical technique can be used to improve spin-transfer switching of magnetic layers, using transport and optical techniques to measure the relevant properties. They will have the opportunity to work with two large-scale facilities which the research division is responsible for, the Tandem laboratory based in Uppsala, for ion-beam analysis, and the SuperADAM neutron reflectometer based at the Institut Laue-Langevin in Grenoble, France.
