Abstract

Uniaxial magnetic anisotropy has been observed in La_0.7Sr _0.3MnO₃ thin films grown on top of multiferroic BiFeO ₃ with ferroelectric stripe domains (see Figure). The magnetic easy axis of La_0.7Sr_0.3MnO₃ correlates with the ferroelectric stripe domains. A possible spin coupling model at the La _0.7Sr_0.3MnO₃/BiFeO₃ interface is established between ferromagnetic and antiferromagnetic orders to explain this phenomenon.
