  Ferromagnetic SrRuO3 thin films are deposited on the ab-surface of single
crystals of the spin-triplet superconductor Sr2RuO4 as substrates using pulsed
laser deposition. The films are under a severe in-plane compressive strain.
Nevertheless, the films exhibit ferromagnetic order with the easy axis along
the c-direction below the Curie temperature of 158 K. The electrical transport
reveals that the SrRuO3/Sr2RuO4 interface is highly conducting, in contrast
with the interface between other normal-metals and the ab-surface of Sr2RuO4.
Our results will stimulate the investigations on proximity effects between a
ferromagnet and a spin-triplet superconductor.
