Abstract: Sr2RuO4 is a leading candidate for equal-spin triplet pairing with p-wave chiral symmetry. This study presents a method for fabricating mesoscopic structures of Sr2RuO4. The samples are contacted by conventional electron beam lithography methods. A measurement set-up using a vector magnet cryostat was prepared for transport measurements. We observe a high residual resistance ratio indicating high sample quality. The onset of signs of superconductivity appear at 1.5 K, as expected. Crystals with a thickness below 20 nm are found to be insulating, the origin is currently not understood.
