抄録	Based on the Ginzburg-Landau functional of Eu symmetry presented by Agterberg, vortex states of Sr2RuO4 are studied in detail over Hc1 ≤ H ≤ Hc2 by using the Landau-level expansion method. For the field in the basal plane, it is found that (i) the second superconducting transition should be present irrespective of the field direction, (ii) below this transition, a characteristic double-peak structure may develop in the magnetic-field distribution, and (iii) a third transition may occur between two different vortex states. It is also found that, when the field is along the c axis, the square vortex lattice may deform through a second-order transition into a rectangular one as the field is lowered from Hc2.
