Transition metal oxides with metastable phases: a way towards superior ferroic properties

The growing market of consumer electronics and related industrial applications require a wide spectrum of cost-effective functional materials with controllable properties. Recent ecological regulations stimulate utilizing novel lead-free materials with physical parameters comparable to or exceeding commonly used lead-based piezoeletrics. Compounds based on transition metal oxides are considered as the most promising eco-friendly functional materials to be used in magnetic memory or energy storage devices, energy transfer moduli, tunable microwave resonators, phase shifters and other electronic devices and sensors. Additionally, magneto-electric coupling specific for ferrites allows to use them as energy converters and energy harvesting devices. Photovoltaic properties of BiFeO3-based materials disclose novel opportunities in solar cells designing. Declared properties of the materials studied within the Project (complex oxides with perovskite structure) permit to improve the functionality of existing electrical devices via formation of metastable states. Tunability of the electric, magnetic, transport parameters and magnetoelectric coupling provides an effective method to enhance perspectives of practical applications where special attention is focused on the magnetic field sensors for the magnetic memory storage devices. TransFerr Project aimed to design and study novel functional materials with multiferroic properties required in electric applications. It was focused on the two main approaches to create metastable structural states: (i) to design compounds based on novel ceramic compositions via chemical substitution and proper post-synthesis treatment, and (ii) to exploit chemical routes for the synthesis of thin films and nanoceramics. The research permitted to design novel functional materials with pronounced and controllable physical properties. The consortium Partners increased their knowledge and skills in the area of innovative multifunctional materials through results dissemination and extensive transfer of the experience in complementary subjects.

Project objective

The main objective of the project is development of complex transition metal oxides with perovskite-like structure having improved and controllable (multi)ferroic properties. The mentioned materials are manganites and ferrites with optimal composition having distinct magnetization, polarization, (magneto)transport properties or magnetoelectric coupling. The idea of the project is to utilize reduced structural stability of these oxides which increases their sensitivity to external stimuli. Improved functional properties of these oxides can be controlled via modification of the chemical bond character, structural parameters, stoichiometry, defects etc. The reduced stability is associated with the metastable structural state formed in the vicinity of the phase boundaries, while this state presumably consists of coexistent nanoscale regions of the adjacent structural phases. There are two ideas to create metastable state: the first one – to design ceramics via chemical substitution and post-synthesis treatment by high pressure and/or thermal cycling in gases to induce nanoscale regions, the second one assumes chemical routes synthesis of films and ceramics. Besides the fundamental interest of the phase transitions and related phenomena affecting properties of the oxides the applicants consider them to be effective materials for electronic applications (as sensors, magnetic memory elements, filters etc.). Research of these oxides requires consolidative efforts of specialists in different scientific areas - Materials Science, Theoretical Physics, Solid State Physics etc. as well as an access to unique equipment and facilities. Another important objective of the project is a formation of interdisciplinary network of teams and specialists with different scientific backgrounds which will ensure effective transfer of actual knowledge and skills. Development of the transition metal oxides with controllable properties has promising commercial opportunities for the involved SME.
