Figure 1. Sketch of the sample, crystal structure and the polarizations of PMN-PT.

Figure 1

(a) Configuration of the heterostructure, piezoresponse of the PMN-PT substrate and the easy axis of magnetization of the CoFeB layer under electric fields. (b) The unit cell and spontaneous polarizations of (011) oriented PMN-PT. (c), (d) and (e) Top view of the polarizations and deformation of the (011) crystal plane in PMN-PT substrate for the virgin state (c), under electric fields (d) and after removing electric fields (e). The slender arrows in (b), (c), (d) and (e) with the same color represent the same spontaneous polarizations of rhombohedral PMN-PT.
