Аннотация: A generalized t-J-I-model is proposed for Sr2RuO4 that takes the strong intra-atomic correlations of the d electrons and the features of the electronic structure of Sr2RuO4 into account. It is shown that, in the limit of strong correlations, there are no singlet s-type solutions for the superconducting state, but triplet solutions exist because of ferromagnetic spin correlations. For typical values of the model parameters, T(c)similar to 1 K, consistent with the value of T-c for Sr2RuO4. (C) 1999 American Institute of Physics. [S1063-7834(99)00511-0].
