We have investigated the magnetic response of La0.7Sr0.3MnO3/SrRuO3superlattices to biaxial in-plane strain applied in-situ. Superlattices grownon piezoelectric substrates of 0.72PbMg1/3Nb2/3O3-0.28PbTiO3(001) (PMN-PT) showstrong antiferromagnetic coupling of the two ferromagnetic components. Thecoupling field of mu0HAF = 2.8 T is found to decrease by deltaHAF/delta epsilon~ -520 mT %-1 under reversible biaxial strain mu0HAF at 80 K in a[La0.7Sr0.3MnO3(22)/SrRuO3(55)]15 superlattice. This reveals a significantstrain effect on interfacial coupling. The applied in-plane compressionenhances the ferromagnetic order in the manganite layers which are underas-grown tensile strain. It is thus difficult to disentangle the contributionsfrom strain-dependent antiferromagnetic Mn-O-Ru interface coupling and Mn-O-Mnferromagnetic double exchange near the interface, since the enhanced magneticorder of Mn spins leads to a larger net coupling of SrRuO3 layers at theinterface. Strain-dependent orbital occupation in a single-ion picture cannotexplain the sign of the observed strain dependence, whereas the enhanced Mnorder at the interface is qualitatively in line with it.
