Report on the organisation of the Topical Session “Materials for spintronics” during
the 17th International Conference on Crystal Growth and Epitaxy,
Warsaw, August 11-16, 2013,
within the framework of European Action
towards Leading Centre for Innovative Materials.

As a part of the effort to build up EAgLE’s visibility through promotion and dissemination activities, the first planned activity of Work Package 6, the task 6.5: Organization of Topical Session T-02 at the 17th International Conference on Crystal Growth and Epitaxy – “Materials for spintronics”, took place in Warsaw on August 11 - 16, 2013.

Logo of 17th International Conference on Crystal Growth and EpitaxyThe parent conference is a long going event which gathers every third year (usually) about a thousand scientist from all over the world and is regarded as the most important event in this part of the material science society which is scientifically and professionally oriented on all aspects of growth of high quality crystalline materials for industry and academia. ICCGE has been providing the forum for presentations and discussions of the recent research and development activities in all aspects of bulk crystal growth and epitaxial thin film growth covering fundamental issues, experimental and industrial growth processes, characterization and applications.

The conference gathered 860 registered participants from all 5 continents and to keep all of them in focus the scientific program of the conference was divided into 9 plenary lectures given in the mornings of the first 4 days of the ICCGE then 10 general sessions and finally 9 topical sessions. The latter were held in parallel giving a choice to choose from four different topics. The sessions were accompanied by two general poster sessions with posters grouped in accordance to their subjects.

Topical Session T-02: Materials for Spintronics

The aim of the Session was to focus on the challenges of growth of spintronic materials including magnetically doped nitrides, arsenides, oxides, II-VI compounds and diamond. The Sesion provided a forum to discuss issues related to various characterization methods involving transport, magnetometry, optics, electron, and X-ray diffraction, microscopy, and tomography as well as spectroscopic optical and synchrotron-radiation methods. All in view for perspective for possible spintronic devices and applications. By gathering the leading figures in this field the forum provided a platform for further exchange of knowledge and collaboration among leading centers aiming to bring the spintronic concepts and promises closer to industry-wide applications. The session was coordinated jointly by Prof. Maciej Sawicki (Institute of Physics, Warsaw) and Prof. Fumihiro Matsukura from Tohoku University in Sendai, Japan. Early in 2013 the coordinators selected two prestigious invited speakers to set up the main theme of the meeting: Prof. Alberta Bonanni from Johanes Kepler University in Linz, Austria and dr. Richard Campion from Nottingham University in Great Britain.

Following the early year call for 28 abstracts directed to T-02 session were obtained. During evaluation process all of them have been accepted and a selection was made for oral and poster presentation. As the result 10 papers were suggested to be presented as short (15 minutes) presentations, what together with the two invited talks made 12 oral presentations at the T-02 sessions. To promote vivid discussions as well as to give the ability to confront the current state of the IF PAN research in growth of spintronics materials with the leading world experts half of the session speakers (6) were selected to be from IF PAN. Importantly, the two key invited lectures were given by foreign guests. The session was allocated by the ICCGE-17 program committee to be held on Friday morning, August 16th, and was divided into two subsessions according to the following schedule:

The financial effort of the EAgLE towards Session T-02 was reflected by the visual and spoken acknowledgements made by the supported participants during their presentations. The following table gives some examples of the EAgLE visibility during T-02 session, and so during the whole ICCGE-17.
