November 19, 2021 feature Low-voltage magnetoelectric coupling in membrane heterostructures . by Thamarasee Jeewandara , Phys.org Anisotropic strain in (011)-oriented PMN-PT. (A) Cartesian coordinates x, y, and z are defined to be the crystal [100],[011?], and [011] directions, respectively. Polarization directions in (011)-oriented PMN-PT unit cell, grouped into rhombohedral in-plane (RIP; orange), rhombohedral up (RUP; blue), and orthorhombic up (OUP; purple). Rhomboh...
