Neutron Diffraction Studies of Magnetic and Superconducting Compounds
Neutron diffraction is an extremely valuable tool for the investigation of magnetic and superconducting materials, because of its ability to directly observe periodic magnetic structures, determine magnetic moment directions and magnitudes, to observe light elements that are otherwise difficult to locate from X-ray diffraction due to the strong scattering of heavy elements, or to distinguish nearby elements in the periodic chart. This talk will focus on recent studies of superconducting and magnetic oxides that may provide insight into the interaction of magnetism and superconductivity, and into important changes in other transport properties (colossal magneto-resistance, ionic conductivity, etc.). These materials appear to show promise for a wide range of applications, and the neutron studies may not only help to understand their properties, but may also provide direction for synthesis of compounds that may overcome the limitations of those already discovered.
