Abstract: Eutectic samples of Sr2RuO4-Ru possess many micrometer-sized Ru-metalinclusions. Based on a Ginzburg-Landau formulation we analyze the interplay ofthe chiral p-wave state of Sr2RuO4 Tc = 1.5 K and the s-wave state of Rumetal Tc,Ru = 0.5 K for an inclusion of cylindrical geometry. As aconsequence of the mismatch of the order parameter phase, the occurrence of aspontaneous flux distribution appears for T < Tc,Ru which evolves into a-Josephson vortex- on the Sr2RuO4-Ru interface. At a sufficiently lowtemperature a depinning transition can occur whereby the vortex moves to thecenter of the cylinder.
