Figure 5. (A) Schematic of the screen surrounding the pump laser spot with the top of the crystal (gold color) and a sketch of the charge distribution (the free charge is enclosed within the circle)[111]. (B) The out-of-plane polarization (P3) of BTO (001) films is a reflection of the in-plane (H1) and out-of-plane (H3) magnetic field strength for different biaxially isotropic in-plane residual strains ε0 (= ε11 = ε22)[115]. BTO: BaTiO3.
