Abstract

A new orthorhombic phase of the multiferroic ${BiFeO}_{3}$ has been created via strain engineering by growing it on a ${NdScO}_{3} (110)_{o}$ substrate. The tensile-strained orthorhombic ${BiFeO}_{3}$ phase is ferroelectric and antiferromagnetic at room temperature. A combination of nonlinear optical second harmonic generation and piezoresponse force microscopy revealed that the ferroelectric polarization in the orthorhombic phase is along the in-plane $⟨ 110 ⟩_{pc}$ directions. In addition, the corresponding rotation of the antiferromagnetic axis in this new phase was observed using x-ray linear dichroism.
