Final aim of the project:
the increase of competitiveness of the research-development-innovation (RDI) sector from the field of magnetic materials, highly corrosion-resistant and with enhanced endurance, the enhancement of the sector of top technologies in the field of spin electronics as well as creation of technologies and advanced-innovative magnetic materials with strong applicative potential in industry and economy.

Main objectives:

  1. The transition from fundamental research of the advanced magnetic materials, to the creation and testing of nanometric scale devices, with conception and elaboration of permanent magnets of high TC and highly corrosion-resistant, magnetic tunnel junctions (MTJ) and spin valves, for the IT,
  2. Promotion of a wide scale knowledge dissemination of the high level scientific results, based on the multidisciplinar research strategy of the Consortium, as well as enhancement of the impact of the Romanian achievements in the field, to the international scientific community and integration into ERA,
  3. Approach of a high scientific level for nano-magnetic advanced materials and global strategies for implementation in devices with applicative potential,
  4. Implementation of viable strategies of integration into devices with high applicative potential of advanced materials with superior properties and completely new architectural solutions.
  5. Use of modern processing methods; tackling new techniques to create products and clean technologies with impact on judicious use of raw materials and environment preserving.

Specific objectives:
Implementation of viable strategies of integration into devices with high applicative potential of the following materials:

  1. Colloidal core-shell NP’s that exhibits GMR effect, soft magnetic nanowires grown from porous media support, assembled into periodic structures via self-organization.
  2. Nanocomposite magnetic materials with multiple phases, based on FePt-type alloys, with perspectives for applications in the field of high-TC permanent magnets, highly corrosion-resistant.
  3. Multiphased materials with antiferromagnetic – ferromagnetic interactions that exhibit TMR effect, with perspectives of applications as MTJs and spin valves.

Novelty/originality elements:
- Creation of the implementation mechanisms of self-organized nanostructures, NP’s, nanowires and low-dimensional systems with high degree of ordering and reproducibility, in innovative technological products and high applicative potential devices;
- Implementation of testing/application methodologies and of viable strategies for developing a new class of multifunctional multiphased magnetic materials with properties which derive from inter-phase magnetic interactions, such as: exchange coupled magnets with high energy product and high corrosion resistance for oriented technological applications

Beneficiaries of the results:
The potential beneficiaries of the scientific results will be first of all national and international scientific communities. The project final aim is to conceive and execute devices with integrated GMR cells, MTJ’s, creation of advanced nanocomposite magnets used in generators of modular structure for new sources of alternative energy. The results may have a fast economic effect by implementation into mass-production. Also, the project may contribute to the development of new and advanced technologies, for a sustainable economic growth, based of production of goods (devices, materials and nano-system) with high added value.
