Synopsis

This project will investigate puzzling complex phenomena in multiferroics with the aim of designing new multiferroic materials for the possibility of using them in novel applications. Many compounds will be studied which will reveal the atomistic interactions that are responsible for the electrical polarization of rare-earth orthoferrites and orthochromites, as well as novel multiferroics via defect-engineering. Investigations of polarization switching in e.g. BiFeO3 thin films, which is crucial for designing memristors will also be carried out. Further, doped FeO3 structures will be studied to explore  materials having a negative index of refraction as well the possibility of giant energy storage density in compounds. A broad and deep knowledge of multiferroics and complex phenomena in bulk and nanomaterials will be gained, which has the potential to lead to the realization of devices with enhanced and/or new functionalities, and that will improve energy efficiency and storage.
