Studium nových silně korelovaných elektronových sloučenin REnTIn3n+2
Bartha, Attila ; Kratochvílová, Marie (advisor) ; Pospíšil, Jiří (referee)
We have studied two different systems; RE2CoIn8 (RE = Pr, Nd, Dy) and CenTIn3n+2 (T = Pd, Pt; n = 2, 3). All compounds were prepared for the first time in the single crystalline form using the self-flux method. X-ray diffraction confirmed the tetragonal Ho2CoGa8 structure type for the RE2CoIn8 compounds and for the new phase Ce2TIn8. The novel phase Ce3PtIn11 adopts the structure of the Ce3PdIn11 compound, which represents a new structure type. Magnetic measurements revealed low anisotropy and the c-axis as the easy axis for all RE2CoIn8 compounds. Pr2CoIn8 is a paramagnet, while Nd2CoIn8 and Dy2CoIn8 order antiferromagnetically. Magnetization and specific heat measurements of Dy2CoIn8 revealed complex magnetic field-temperature phase diagram with various types of magnetic ordering. Specific heat measurements on multiphase Ce-Pd-In system revealed superconducting transition at Tc = 0.69 K arising from Ce2PdIn8 and another magnetic transition from Ce3PdIn11 at ~ 1.7 K. Ce3PdIn11 and Ce3PtIn11 compounds reveal two, probably magnetic transitions at T1 = 1.6 K, T2 = 1.45 K and T1 = 2.1 K and T2 = 2.0 K, respectively. Specific heat data qualifies both materials as heavy fermion compounds with γ = 290 mJ.mol-1 Ce K-2 and γ = 300 mJ.mol-1 Ce K-2 respectively.

Studium magnetických a termodynamických vlastností ternárních sloučenin se silně korelovanými 4f elektrony.
Kratochvílová, Marie ; Pospíšil, Jiří (advisor) ; Custers, Jeroen (referee)
We have studied two different systems of compounds, YPd2Al3 and CenTmIn3n+2m. Polycrystalline YPd2Al3, a new member of the REPd2Al3 system, was prepared by arc melting. The X-ray diffraction confirmed that YPd2Al3 crystallizes in the hexagonal PrNi2Al3-type structure as the other REPd2Al3 compounds. Magnetization, AC susceptibility, specific heat and resistivity measurements revealed superconductivity below Ts ≈ 2.2 K. The second part of the work was focused on studies of Ce2PdIn8 and Pd-doped CenRhIn3n+2. Single crystals of Ce2Rh1-xPdxIn8 with x = 0, 0.10, 0.15, 0.30, 0.45, 0.85, 1 and CeRh1-xPdxIn5 with x = 0, 0.1, 0.25 were prepared by solution growth method. The quality of crystals was confirmed by microprobe analysis and X-ray diffraction. The effect of Pd doping on magnetism of CenRh1-xPdxIn3n+2 was studied by specific heat, magnetization and resistivity measurements. The Pd doping gradually suppresses the Néel temperature in both systems, however the effect is stronger in Ce2Rh1-xPdxIn8. Temperature dependence of resistivity of CeRh0.75Pd0.25In5 was studied in pressure up to 2.2 GPa. Similar to CeRhIn5, the antiferromagnetism is gradually suppressed by the applied pressure, while superconductivity is induced and coexists with antiferromagnetism.

Practising of verbal forms in the education of Czech for foreigners
Kratochvílová, Marie ; Chejnová, Pavla (referee) ; Janovec, Ladislav (advisor)
The essay deals with the morphological exercises of Czech for foreignes, especially with the conjugatin of verbs. It outlines which exercises could be used for morphology education of Czech as a Foreign Language and it shows which exercises are most beneficial for the initial training of this aspekt od the language and which ones could be used for further training and revision. To learn conjugation in Czech we do not only use exercises such as gap fill, substitution or sentence completion exercises, but we can make use of a lot of language games and activities, which by nature come closer to natural communication. By using concrete exercises, we show how to train the language the best. The theoretical part points out the factors influencing the choice of exercises and shows the most frequent types of exercises to be used for learning a foreign language. The practical part briefly deals with the nouns - categories of numbers, gender, category o f animata / inanimata, because these factors have a major impact on forming the verbs. In the practical part, which is devided into chapters according to the single steps o f learning the verbal forms (Present tense. Past tense. Future tense Conditional, Imperative), we can find a lot of concrete exercises with comments evaluating their use in the education of Czech...

Štěrková zahrada
Kratochvílová, Marie
Diploma thesis "Gravel Garden" deals with the problematics of construction and working of gravel gardens as one of contemporary trends in designing private gardens according to the principles of natural plant communities. Literary part of the thesis provides a definition of "gravel garden" and refers about principles of design, construction technologies, characteristics of mineral materials and plants for use in gravel gardens. That is shown by the representative examples of implementation in the Czech republic and abroad. The thesis also presents the possibility of using technologies in the future. Knowledge is applied in the design of the model object of private garden with show gardens of family nursery in the village of Dub nad Moravou.

Problematika odložené daně
Kavan, Ctibor ; Kratochvílová, Marie (advisor) ; Zelenka, Vladimír (referee)
Tato práce se snaží postihnout základní aspekty a principy účetní kategorie odložené daně. V úvodní části je popsána obecná podstata odložené daně, příčiny jejího vzniku a důvody pro účtování o odložené dani. Největší část této práce se věnuje problematice odložené daně, jak je řešena v Mezinárodním účetním standardu č. 12 ? Daně ze zisku, jelikož tento standard precizně vymezuje problematiku odložené daně a jeho vliv je patrný i v národních účetních legislativách. V závěrečné části práce jsou popsány metody výpočtu odložené daně a vývoj právní úpravy odložené daně v České republice.
