本文报道了在自旋三重态超导体Sr_2RuO_4的解理面上外延生长的巡游铁磁体SrRuO_3薄膜的磁性。该薄膜表现出铁磁转变在160 K附近的散装SrRuO3，虽然该薄膜是在1.7%的压缩应变。观察到的磁化强度甚至高于散装SrRuO3。此外，我们发现磁场去除后的磁化弛豫是强各向异性的：当磁畴沿沿着ab面排列时，涉及两个弛豫过程。
We report magnetic properties of epitaxial thin films of the itinerant ferromagnet SrRuO3deposited on the cleavedabsurface 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 theab-plane.
