Measurements outside resonance with piezoresponse force microscopy [PDF]
AIP Conference Proceedings, 2021 In this work, we report the advantages of following a protocol to perform measurements of piezoresponse force microscopy (PFM) away from the tip-sample contact resonance. The protocol established in this work is based on Soergel's work [J. Phys. D: Appl. Phys. 44 (2011) 464003]. PFM measurements out-of-plane were carried out in the range of 10-100 kHz.

Magnetoelectric BaTiO<sub>3</sub>/CoFe<sub>2</sub>O<sub>4</sub> Thin-Film Meshes for Neuronal Differentiation. [PDF]
Adv Sci (Weinh)We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Single frequency vertical piezoresponse force microscopy [PDF]
Journal of Applied Physics, 2021 Piezoresponse force microscopy (PFM) uses a cantilever arm to track the electromechanical motion of the electric dipole moment to visualize the ferroelectric domain structure, which provides an important insight into the physics of switchable electric polarization—especially for memory devices and integrated microelectronics. Here, I provide a tutorial

Sequential piezoresponse force microscopy and the ‘small-data’ problem [PDF]
npj Computational Materials, 2018 AbstractThe term big-data in the context of materials science not only stands for the volume, but also for the heterogeneous nature of the characterization data-sets. This is a common problem in combinatorial searches in materials science, as well as chemistry.

Nanoelectromechanics of polarization switching in piezoresponse force microscopy
Journal of Applied Physics, 2005 Nanoscale polarization switching in ferroelectric materials by piezoresponse force microscopy in weak and strong indentation limits is analyzed using exact solutions for coupled electroelastic fields under the tip. Tip-induced domain switching is mapped on the Landau theory of phase transitions, with domain size as an order parameter.
