The double-perovskite oxides Ca2FeMoO6, Sr2FeMoO6 and Ba2FeMoO6 show evidence of ferromagnetic metallic behaviour, with Curie temperatures of 345-426 K and saturation magnetization of 3.5-3.9 µB/formula unit. Ceramics show little anisotropic magneto

Microstructures of high-Tc Bi-based superconductors in a disk form and a tape form sheathed by Ag are examined by SEM and TEM. The disk specimens were prepared by the sol-gel method and are compact with few cavities. Bi-2212 or Bi-2223 grains grow wi

Low temperature heat-capacity measurements have been performed to study the magnetic ordering in NdBa2Cu3O x and DyBa2Cu3O x . In order to investigate the type of ordering, magnetic fields up to 6 T and hydrostatic pressures up to 4.5 kbar were appli

Two sol-gel (citrates and acetates- derived) methods for the 2223 BiSCCO precursor powders and film preparation were studied. The acceleration of diffusion processes due to intimate cation mixing and homogeneity on atomic scale provides the effective

A polymer-cement system was produced by in situ polymerization of vinyl sulphonate in Portland cement pastes and mortars. The effects of the polymer on strength, chloride diffusion and microstructure were studied. The presence of polymer was found to
