Tailoring Macroscopic Functionalities in a Semiconducting Oxide
In project C9 we aim at controlling both the steady and the transient functionalities in the ferromagnetic oxide semiconductor EuO. Two complementary approaches will be employed: advanced crystal engineering - to control the steady state, and femtosecond optical excitation - to control the transient state. The advanced engineering approach relies on the preparation and characterization of EuO thin films in different lateral configurations and dimensions to generate epitaxial strain, proximity, or quantum confinement effects. As a following step, we will employ time-resolved magneto-optical and photoemission experiments to explore the femtosecond electron and spin dynamics with the main aim of manipulating the magnetic order in the steady-states induced via advanced crystal engineering.
