Abstract

Uniaxial magnetic anisotropy has been observed in La0.7Sr 0.3MnO3 thin films grown on top of multiferroic BiFeO 3 with ferroelectric stripe domains (see Figure). The magnetic easy axis of La0.7Sr0.3MnO3 correlates with the ferroelectric stripe domains. A possible spin coupling model at the La 0.7Sr0.3MnO3/BiFeO3 interface is established between ferromagnetic and antiferromagnetic orders to explain this phenomenon.
