摘要
The electronic energy band structure for Sr3Ru2O7, which is related to the superconducting Sr2RuO4 and whose structure is called double-layered structure, has been calculated by using the scalar-relativistic full-potential linearized augmented plane wave (FLAPW) method within the local-density approximation in the paramagnetic case. The result of the calculation suggests that this compound is a metal and its electronic structure looks like that of Sr2RuO4. However, we found one of the Fermi surfaces has a large dispersion along k(z) axis. The calculated large density of states at the Fermi energy indicates that Sr3Ru2O7 may have a ferromagnetic ground state.
