Magnetization dynamics induced by photons, phonons and electrons in (Ga,Mn)As
Abstract
Ga,Mn)As is a semiconductor doped with a small percentage of magnetic atoms that behaves in many way like a « real » ferromagnet. Although its Curie temperature has remained too low to use it for applications, I will show how it has nevertheless served as a model system to test various strategies to improve magnetic data storage and logic. In particular, I will show that pulsed magnetic fields, currents, light and strain can trigger efficiently magnetization dynamics.
