Abstract

Complex oxides exhibit an exceedingly wide range of electronic, magnetic and optical properties, giving these materials considerable potential for interesting basic science investigations, as well as possible utility in a range of technological applications. Complex oxides have been vigorously investigated as epitaxial films over the past two decades, in part because of the discovery of high-Tc superconductivity in cuprates . A second reason for this interest is the rich and varied property set, including colossal magnetoresistance , exhibited by the doped manganites, AExRE1-xMnO3, where AE and RE represent alkaline earth and rare earth metals, respectively. The observations of many interesting and often unexpected phenomena have captured the attention and imagination of a growing community of condensed matter scientists who wants to explore the fundamental physics of these materials, as well as novel technological concepts.
