| In order to elucidate the origin of anomalous metallic state observed in UBe13, the heavy fermion superconductor Th substituted compounds Th1-xUxBe13 should be thoroughly studied.
So far strange single-uranium-site effect in uranium-diluted system Th1-xUxBe13 for x ≤ 0.11) has been observed. The main objective of the PhD work is extension of the study on the entire range of uranium concentrations. The key part of the work is the growth, structure and composition characterization of high quality Th1-xUxBe13 single-crystals of selected stoichiometries by using the Al-flux method. The crystals should be then subjected to experiments focused on determinarion of intrinsic magnetic, thermodynamic, transport properties. As a result sound information on the origin of the heavy fermion state is espected and clues how to understand the physical properties in periodic system |
