AbstractAbstract
[en] Large bulk Y-Ba-Cu-O superconductors, 62 mm in diameter and 12 mm in thickness, have been fabricated by a cold seeding method in which four seeds are placed on top of the precursor at room temperature prior to melt processing. The advantage of a cold seeding technique is that the desired seeding location can be arranged at room temperature. However, due to the reaction of the seed with the precursor at high temperatures, controlled single-grain growth has been difficult. In the present study, we carefully investigated the influence of the processing parameters such as the maximum heating temperature, the dwelling time at this temperature, the temperature to start slow cooling and the slow cooling rate on the grain growth behavior. Through the optimization of these processing parameters, we have succeeded in growing large bulk Y-Ba-Cu-O with four large grains. The sample with 1 wt% CeO2 addition showed almost the same field trapping ability as a single-domain sample.

AbstractAbstract
[en] It is shown that antiferromagnetic and antiferroquadrupole subsystem mixing takes place in a magnetic field. The increase of antigferroquadrupole transition temperature with the growth of magnetic field in CeB6 is explained by this fact

AbstractAbstract
[en] Using the numerical renormalization group method, we study a generalized two-channel Kondo model where the impurity has a quadrupole moment (pseudospin) and a magnetic moment (flavor). This model may be of relevance to the Ce ions in CeB6 and the Cu ions in cuprate superconductors. We find that the nontrivial fixed point of the two-channel Kondo model is unstable against flavor exchange coupling. The system flows to a non-Fermi-liquid fixed line. In the presence of a double tensor interaction, which breaks particle-hole symmetry, the system flows to a Fermi-liquid fixed line

AbstractAbstract
[en] The Ce2O3-SO3-H2O system has been studied at 20 dea C by the solubility method. The polytherm of the system in the range of 2O-200 deg C has been plotted. The solubility of serium (3) sulfates is rather low and normally not higher than 0.1-0.3% Ce2O3 over a large interval of SO3 concentration, the only exception being the low concentration region where solubility attains 5.53% Ce2O3
