Fifth-two papers from November 1999 symposium present new research and applications in magnetic oxide materials. The main topics are spin polarization and tunneling, transport and optical properties, two-phase coexistence in the manganites, strain effects in manganite thin films, and magnetic oxide heterostructures. Some of the topics are growth of colossal magnetoresistance heterostructures by molecular beam epitaxy, magnetism and CMR in electron doped perovskite and layered manganites, spectroscopic studies of inhomogenous electronic phases, lattice distortions and domain structure in epitaxial manganite thin films, and deposition and electrical characterization of dielectric/ferromagnetic heterostructure.
