Figure 1. Morphologically engineered artificial multiferroic heterostructure.

Figure 1

(a) Schematic of the heterostructure of a patterned nanomagnet with four-fold shape symmetry grown on a ferroelectric layer (e.g., (011)-PMN-PT). (b) The top view of the Ni nanomagnet on the ferroelectric layer, where y axis denotes the main direction of in-plane anisotropic piezostrain and α the angle between y axis and one of the long axes of the Ni nanomagnet. The blue dashed line represents the shape anisotropy energy contour. (c) Four possible magnetization vector distributions in an as-grown nanomagnet.
