  We report magnetic properties of epitaxial thin films of the itinerant
ferromagnet SrRuO3 deposited on the cleaved ab surface of the spin-triplet
superconductor Sr2RuO4. The films exhibit ferromagnetic transition near 160 K
as in the bulk SrRuO3, although the films are under 1.7% compressive strain.
The observed magnetization is even higher than that of the bulk SrRuO3. In
addition, we newly found that the magnetization relaxation after field removal
is strongly anisotropic: two relaxation processes are involved when magnetic
domains are aligned along the ab-plane.
