The X-ray group consists of three teachers, two research workers and one X-ray specialist operating with six automatic (or additionally automated) powder diffractometers and one X-ray unit for film recording. Special attachments are used for studies of thin films (Guinier camera, Seemann-Bohlin goniometer, parallel beam grazing incidence), textures (Eurelian cradles and rotating devices) and for studies in nonambient temperatures (special chambers for X-ray work in the range from 4 K to 2000 K, position sensitive detector). Software codes for the Rietveld method, Fulprof, Treor, Lazy Pulverix, Crystal Office, Suprex, Distorted Wave Born Approximation (DWBA) and the ICDD database PDF2 are available.
The research work is concentrated on studies of structure of thin films, structure of magnetic metallic multilayers and on the investigation of reaction diffusion processes in nitrides of transition metals. However, many other smaller projects are usually running parallel, like nanocrystalline materials, intermetallics, high Tc superconductors, graphitic cermets, texture, profile analysis, application of the effect of anomalous dispersion. Our main cooperating partners are from the Academy of Sciences of Czech Republic in Prague, Masaryk University in Brno and from universities in Vienna, Regensburg and Medoun.
The members of the X-ray group are teaching crystallography and structure analysis in the field of solid state physics and biophysics. Special lectures are devoted to thin films, surfaces, single crystal work, dynamical theory, real structure studies, modern analytical methods, computer nets and computer calculus.
