Electronic structure of high temperature superconductors

OSTI ID:6165430
Electronic structure calculations on high temperature superconductors using the Linear Muffin Tin Orbital (LMTO) method are presented. The LMTO method, a first principles electronic structure method based on density functional theory, is briefly reviewed. Results are then presented for three different applications. First, applications of the method to structural and magnetic properties of La/sub 2/CuO/sub 4/ are presented. Next, calculations on bismuth-containing copper-oxide superconductors are discussed. These motivate a discussion of the importance of interlayer coupling for superconductivity. Finally, oxygen ordering in the YBa/sub 2/Cu/sub 3/O/sub 7/minus/y/ system is considered by using first principles calculations to determine the effective pair interactions for use in statistical mechanical models of system. 29 refs., 5 figs.
