Published: Dynamic Electrical Response of Vortex Polarization in PST/STO Superlattice Thin Films

Our paper entitled “Dynamic Electrical Response of Vortex Polarization in (Pb0.9Sr0.1)TiO3/SrTiO3 Artificial Superlattice Thin Films” has been published in Appl. Phys. Lett. We found that the reorientation of dipole moments in the vortex domains is susceptible to the applied electric field pulses of 500 μs and is a reversible process. Although the centrosymmetric vortex domain structure is not considered to exhibit piezoelectricity, an evident change in the out-of-plane lattice constant with the applied electric field was revealed.
