ABSTRACTThe temperature dependent magnetization, M(T), of superconducting BaErCuO and BaYCuTiO was measured via the BTi SQUID susceptometer. In the zero field cooling case, M(T) of BaErCuO was found to be similar to that of Pb. But, M(T) of BaYCuTiO was found to decrease rapidly with T and be almost linear in T. However, in the field cooling case the fluxoids were found to be trapped at all T below Tc, and its amount was found to depend on Ts at which the sample starts to be cooled, as observed in Pb. The ergodic limiting points were not observed within the chosen parameters. The irreversibility of magnetization observed in both BaErCuO and BaYCuTiO is attributed to the fluxoids, trapped during the field cooling process.

После импульсного намагничивания колец прямоугольного сечения из высокотемпературных сверхпроводников измерена величина захваченного поля в зависимости от времени снижения намагничивающего поля. Показано, что, используя обрыв экранирующего тока, можно однократным импульсом намагничивать кольца до максимальной величины, соответствующей процессу охлаждения в поле (field cooling process).

Although sections of frozen salt solutions have been used as standards for x-ray microanalysis, such solutions are less useful when analysed in the bulk form. They are poor thermal and electrical conductors and severe phase separation occurs during the cooling process. Following a suggestion by Whitecross et al we have made up a series of salt solutions containing a small amount of graphite to improve the sample conductivity. In addition, we have incorporated a polymer to ensure the formation of microcrystalline ice and a consequent homogenity of salt dispersion within the frozen matrix. The mixtures have been used to standardize the analytical procedures applied to frozen hydrated bulk specimens based on the peak/background analytical method and to measure the absolute concentration of elements in developing roots.
