Electronic structure of CrO$_2$ probed by NMR and DFT

Autor: Chlan, Vojtěch, Shmyreva, Anna A., Štěpánková, Helena

Electronic structure of ferromagnetic half-metal CrO$_2$ was studied by means of 53Cr nuclear magnetic resonance (NMR) spectroscopy and density functional theory (DFT). The measured NMR spectrum consists of three distinct spectral lines and is interp

Orientation and dynamics of water molecules in beryl

Autor: Chlan, Vojtěch, Adamec, Martin, Štěpánková, Helena, Thomas, Victor G., Kadlec, Filip

Behavior of individual molecules of normal and heavy water in beryl single crystals was studied by $^1$H and $^2$H nuclear magnetic resonance spectroscopy. From temperature dependences of the spectra we deduce that type-I water molecules embedded in

Peculiarities of 57-Fe NMR Spectrum in Micro- and Nanocrystalline Europium Orthoferrites

Autor: Sklyarova, Anastasia, Popkov, Vadim I., Pleshakov, Ivan V., Matveev, Vladimir V., Stepankova, Helena, Chlan, Vojtech

NMR spectra of 57-Fe dispersed europium orthoferrite in powder samples with micro- and nanocrystalline particles were studied for the first time. The material was synthesized by glycine-nitrate combustion, which allowed to obtain the specimens with g

Komparace vývoje stranických systémů ČR, Slovenska a Polska z hlediska teorie cleavages

Autor: Štěpánková, Helena

This diploma thesis deals with a development of the socioeconomic cleavage in the party systems of the Czech Republic, Slovakia and Poland in 2006 - 2012. At the beginning the theory of cleavages by S. Rokkan and S. M. Lipset and the enlargement to p
