General Information
The main objective of the project is the development of new lead-free multiferroic materials for prospective application in forms of films and/or arranged layers in which the cross-coupling (magnetic-dipolar-elastic) can be tuned by both internal and external factors. This objective is to be achieved through preparation, investigation, and optimization of two kinds of Bi-containing oxygen-octahedral (BCOO) systems with paramagnetic ions involved: metastable perovskites and layered double hydroxides (LDHs). The characteristic feature of such materials is the possibility of supplementary control parameters in addition to temperature and external electric/magnetic field. Polarization in such metastable perovskites is easily switched by application of external pressure (or stress in the case of films).
Electric and magnetic characteristics of BCOO LDHs are tuned through appropriate anion exchanges. It makes these characteristics dependent on environment conditions: humidity, pH, and the presence of specific anion species. The BCOO materials of both mentioned groups are of interest as new and unusual multiferroics. No LDH materials have been considered as potential multiferroics so far, while the metastable BCOO materials to be investigated in this project have not been obtained before. Besides, a tuneability and high sensibility of their properties to external impacts make them promising for applications in sensors. The TUMOCS consortium includes complementary expertise in Physics, Chemistry, and Materials Science required for the exploration and development of such materials, with access to and skills in using specific and unique equipment and facilities. Advance in development of the BCOO multiferroics has potential market opportunities for R&D SME involved in this project. The project foresees intensive exchange of staff between the involved partners, which are from both the academic and non-academic sector. Also, staff exchange with a partner organization outside the EU is planned.
