Science and technology of magnetic oxides

Abstract

The symposium, Metallic Magnetic Oxides (Symposium V), was held in Boston, Massachusetts, December 1--4, 1997 as part of the 1997 Materials Research Society Fall Meeting. Research into the science and technology of magnetic oxides has undergone a renaissance during the past seven years. In large measure this stems from the rediscovery of the colossal magnetoresistance associated with the ferromagnetic-order-induced, metal-insulator transition exhibited by the doped lanthanum manganites. Research today is focused both on improving the understanding of the phenomena exhibited by these compounds and on developing technological applications that utilize their extremely magnetic-field-dependent conductivity near room temperature. This symposium focused on colossal magnetoresistance (CMR) materials, including manganites and cobalites. Transport and magnetic properties and their dependence on stress, growth conditions, stoichiometry, and elemental composition are now being explored quite extensively. Forty two papers have been processed separately for inclusion on the data base.
