The Yang–Baxter equation for an SU (2) × U (1)-symmetric spin-orbital chain was solved using the special computer algorithm developed by the author. The seven new R -matrices separated into four groups are presented. Among the obtained integrable models there are special cases related to 1D ferromagnet TDAE-C 60 , 1D superconductors AC 60 (A = K, Cs, Rb), the quarter-filled ladder compound NaV 2 O 5 and the model of correlated electrons on a chain of Berry phase molecules.
