摘要
We introduce a microscopic model for the compound Sr2RuO4, which is at the present the only known layered-perovskite superconductor without copper. The one-particle Hamiltonian is deduced by means of an approach that combines the extended Huckel theory and the tight-binding method. Adding two-body terms to this Hamiltonian, as the local Coulomb interaction and the Hund coupling, the magnetic properties are determined. It is found that the system is close to a ferromagnetic instability and this result supports a superconducting phase with p-wave symmetry.
