Thin film combinatorial studies of functional magnetic materials — •Nora Dempsey — Institut NEEL, CNRS/UGA, Grenoble, France

Combinatorial studies based on the preparation and characterisation of compositionally graded thin films are being used for the screening and optimization of a range of functional materials [1]. When combined with Machine Learning (ML), such high-throughput film-based studies hold much potential to guide data driven design of new materials [2,3]. In this talk I will outline our work at Institut Néel on high throughput fabrication and characterisation of functional magnetic materials as well as our recent developments concerning data handling and analysis. I will then show examples from on-going studies of the effect of composition and fabrication conditions on both structural and magnetic properties of hard magnetic and magnetocaloric materials. I will finish up by briefly outlining preliminary results from ML-driven data analysis for the accelerated development of functional magnetic materials with reduced dependence on critical elements, carried out in the framework of various collaborations.
