Characterization of applied magnetic materials for industrial scale products

For a strong European Research Area it is necessary to allow European nanotechnologies industry to strengthen its competitiveness and to stay competitive with the rest of the world, which is investing massively in the field of nanotechnologies. Therefore, there is a demand in Europe to improve the entrepreneurial character of researchers in nanotechnology related field. To accomplish this goal there must be an advanced educational system able to educate diverse and multi-disciplinary skilled research workforces that is capable to turn new fundamental knowledge into novel competitive technologies, in addition to an effective research infrastructure capable of competing at world-class level. Such an educational program could provide at the same time a fertile ground for the scientific exploration of novel physical phenomena that could eventually lead to novel materials and applications. This is the key aspect this proposal addressed by means of novel and inter-disciplinary research training. The project was hereby build on Dr Vavassori longstanding expertise and proven track record in fundamental aspects of nano-magnetism especially: magnetic microscopy, non-destructive magneto-optical measurements as well as the development of advanced experimental tooling including time-resolved magnetometry using fast laser techniques. Within the framework of the here proposed program, his well established fundamental background was complemented with an interdisciplinary and technology-related research profile, by training him in the fields of characterisation methodologies for technologically relevant materials, in particular magnetic materials related to magnetic recording. The enhancement of competence and skill diversification of the beneficiary, the present proposal's aim, had been progressively achieved through three main steps: - (i): establishment of complementary interdisciplinary expertise at an advanced level in the field of technological relevant materials for magnetic recording and, more specifically, for PMR applications; - (ii): establishment of interdisciplinary and inter-sectorial expertise at an advanced level on the characterisation methodologies utilised for PMR materials; - (iii): test of effectiveness of presently used methodologies by addressing some of the most urgent problems in PMR materials characterization. As a result of this novel educational and research training project, Dr Vavassori gained a solid understanding of state-of-the-art magnetic recording technologies, in particular the technological challenges related to materials issues and materials testing. In addition, he acquired the necessary familiarity with industrial applications related aspects as: product planning, product reliability, patent issues, management and time management skills, as well as negotiation strategies. Concerning data analysis methodologies, Dr Vavassori acquired the necessary knowledge of advanced methodologies utilised for PMR materials with particular emphasis on the ΔH(M, ΔM)-method, which is nowadays considered to be the state-of-the-art methodology to analyse data for PMR technology applications. In terms of scientific and technologically relevant achievement, the main result was the identification, through the comparison with micromagnetic simulations and extensive materials characterisation activity, of directions for improving the ΔH(M, ΔM)-method to cover a broader range of inter-granular interactions, as the inclusion of locally varying inter-granular exchange coupling. Additionally, the key knowledge was transferred to the host institution, CIC Nanogune consolider, and thus enables to consolidate world-leading expertise in this research field within one EU-based research centre. One of the objectives of the present project is to allow Nanogune to maintain its world-wide leadership position in the development and research of characterisation tools for magnetic recording materials.
