The vortex-state complex Hall conductivity (o(sub xy)) of superconducting YBa(sub 2)Cu(sub 3)O(sub 7) epitaxial films is investigated from DC to radio frequencies (up to 7 x 10(sup 6) Hz), using a direct transport measurement technique.
Scanning tunneling spectroscopy was performed at 4.2K on epitaxial thin-film heterostructures comprising YBa2Cu3O7 and La0.7Ca0.3MnO3, to study the microscopic effects of spin-polarized quasiparticle injection from the half-metallic ferromagnetic manganite on the high-Tc cuprate superconductor.

The relevance of lattice distortion, polaron conduction, and double-exchange interaction to the occurrence of colossal magnetoresistance (SMR) is investigated by comparing the physical properties of magnetoresistive manganites and cobaltites.
We report the studies of the Hall effect and magnetic properties in La(0.5)Ca(0.5)Co)(3) thin films and cermaics.
