Neutron scattering and magnetic structure solution

Prof. R.Tellgren- Uppsala, Sweden

As a part of the activities from the WP3: Training in advanced courses the course entitled The course on neutron scattering and magnetic structure solutions was held in the VINCENT Centre during 7th– 11th of November, 2007. The lectures were given by Prof. Dr. Roland Tellgren from the Angstrom Laboratory, Uppsala University (Sweden), who is a peer expert in the field and member of the VINCENT Project advisory board. The course attendants were members of the VINCENT project team, students from VINCENT, as well as one student from Sweden, and four guests from Belgrade University.

Microstructure Analysis by X-ray Powder Diffraction-size and strain effects

Prof. M. Leoni

In the frame of WP3, Prof. M. Leoni visited VINCENT, on May 9-May 12, 2007, and gave lectures on microstructure analysis from the X-ray and neutron powder diffraction data. It was in form of workshop with theoretical part and exercises. The start of the session was devoted to theoretical basis of X-ray line broadening from the very beginning of the method to nowadays improvements. Interesting partly historical story about the Scherrer formulation of the finite crystallite size effect on an X-ray line broadening followed by Warren-Averbach, Williams-Hall and Whole Powder Pattern Modeling methods was presented by Prof. Leoni in a way that all participants were very motivated for further interactive work. In the following practical part of this workshop participants worked in pair (two participants on one PC) on practical problems with aid of Prof. Leoni. Both traditional and Fourier methods were tested on specimens/diffraction data that were supplied by Prof. Leoni (e.g. CeO2, Cu, …) or participants themselves (problems from their own research activity: ferrites, manganites, rare-earth oxides of different composition, etc).
