(a) Dielectric constant of the Ba0.3Sr0.7TiO3 film as a function of temperature under electric fields (experimental data), E (V/µm): (1)—0, (2)—5, (3)—10, (4)—20, (5)—30, (6)—40, (7)—50, and (8)—60. The crystal cell of BaxSr1−xTiO3 (X is Ba or Sr) and shift of the titan atom under bias field (Edc) and it oscillations under microwave field (Emw) are shown in the insert. (b) Dependence of strain vs electric field. Change of Edc polarity results in 180° change of phase of microwave signal.
