We report on transport measurements of Sr2RuO4-Sr3Ru2O7 eutectic crystals. In these systems, natural and clean interfaces are formed between the two phases thanks to the eutectic solidification process. The transport measurements, performed down to 300 mK in a shielded environment, show a clear supercurrent flowing across the interface between Sr2RuO4 and Sr3Ru2O7, also when the contacts are placed at a distance of several hundreds of micrometers from the Sr2RuO4 domain. These results shed light on novel effects appearing in systems composed of the spin-triplet Sr2RuO4 and the metamagnet Sr3Ru2O7, (C) 2007 Elsevier B.V. All rights reserved.

Abstract
We report on transport measurements of Sr2RuO4-Sr3Ru2O7 eutectic crystals. In these systems, natural and clean interfaces are formed between the two phases thanks to the eutectic solidification process. The transport measurements, performed down to 300 mK in a shielded environment, show a clear supercurrent flowing across the interface between Sr2RuO4 and Sr3Ru2O7, also when the contacts are placed at a distance of several hundreds of micrometers from the Sr2RuO4 domain.
