Partner 4: SOLARIS (Jagiellonian University)
Role in the project
Our primary task will be to set up the experimental configuration for advanced characterization, accurate planning each beamtime session to address specific challenges within the system comprehensively.
In addition, our role extends to conducting in-situ and in-operando characterizations that probe the electronic, chemical, and magnetic properties of these materials. This is achieved using synchrotron-based methods, including X-ray Photoemission Electron Microscopy (XPEEM), paired with X-ray Magnetic Circular Dichroism/Linear Dichroism (XMCD/XMLD) to gain specific insights into magnetic ordering. To explore the electronic band structure, we will employ Angle-Resolved Photoemission Spectroscopy (ARPES),
Team qualification in the field of proposal
Our team brings together a diverse and complementary set of expertise in synchrotron science, surface engineering, and advanced data analysis, positioning us as a highly qualified group to address the challenges of this project. Our collective focus on synchrotron-based techniques, especially Photoemission Electron Microscopy (PEEM), enables a deep understanding of both the structural and magnetic properties of materials. By utilizing advanced synchrotron methodologies, including PEEM-XAS, PEEM-XMCD, PEEM-XMLD, and LEED, we thoroughly characterize the complex features and interactions within these systems.
Our work is strongly supported by expertise in molecular beam epitaxy (MBE) for the growth of high-quality thin films, an essential capability for in-situ analysis and patterning processes. These skills allow us to explore and optimize key parameters in the preparation of transition metal oxides and other novel materials, directly impacting their properties and potential applications. Our focus on studying ferrimagnetic-antiferromagnetic (FM-AFM) coupling, particularly through micromagnetic simulations and three-dimensional magnetization maps, is instrumental in advancing our understanding of complex spin dynamics and magnetoelastic effects in magnetic memory technologies.
On the software and analysis front, our team has developed robust Python-based data analysis routines and custom data processing pipelines, enabling precise handling and interpretation of complex datasets collected from PEEM and LEEM techniques. These custom tools, specifically adapted for various PEEM modes, provide critical insights into magnetic and chemical properties and are open-source, allowing for customization based on experimental needs. Moving forward, we aim to integrate machine learning and deep learning methods, demonstrating our commitment to advancing data analysis techniques in line with evolving standards in the field.
As a team, our combined strengths in surface characterization, advanced microscopy techniques, and data-driven analysis make us uniquely suited to contribute to the objectives of the Green-Mem project. Through our collective experience and ongoing collaboration with leading research groups, we ensure our expertise remains at the forefront, enabling high-impact contributions to the study of magnetic materials and surface science.
