Microscopic insights on field induced switching and domain wall motion in orthorhombic ferroelectrics
Ruben Khachaturyan, Yijing Yang, Sheng-Han Teng +3
Surprisingly little is known about the microscopic processes that govern ferroelectric switching in orthorhombic ferroelectrics. To study microscopic switching processes we combine…
Thermal stability of nano-scale ferroelectric domains by molecular dynamics modeling
Arne J. Klomp, Ruben Khachaturyan, Theophilus Wallis +2
Ultra-dense domain walls are increasingly important for many devices but their microscopic properties are so far not fully understood. Here we use molecular dynamic simulations to…
Domain Wall Acceleration by Ultrafast Field Application: An Ab Initio-Based Molecular Dynamics Study
Ruben Khachaturyan, Aris Dimou, Anna Grünebohm
Optimizing ferroelectrics for contemporary high-frequency applications asks for the fundamental understanding of ferroelectric switching and domain wall (DW) motion in ultrafast fi…
Multi-step stochastic mechanism of polarization reversal in orthorhombic ferroelectrics
Yuri A. Genenko, Maohua Zhang, Ivan S. Vorotiahin +5
A stochastic model of electric field-driven polarization reversal in orthorhombic ferroelectrics is advanced, providing a description of their temporal electromechanical response.…
Multi-step stochastic mechanism of polarization reversal in rhombohedral ferroelectrics
Yuri A. Genenko, Ruben Khachaturyan, Ivan S. Vorotiahin +4
A stochastic model for the field-driven polarization reversal in rhombohedral ferroelectrics is developed, providing a description of their temporal electromechanical response. App…
Stochastic model of dispersive multi-step polarization switching in ferroelectrics due to spatial electric field distribution
Ruben Khachaturyan, Jan Schultheiss, Jurij Koruza +1
A stochastic model for polarization switching in tetragonal ferroelectric ceramics is introduced, which includes sequential 90°- and parallel 180°-switching processes and accounts…
Stochastic multi-step polarization switching in ferroelectrics
Y. A. Genenko, R. Khachaturyan, J. Schultheiss +3
Consecutive stochastic 90° polarization switching events, clearly resolved in recent experiments, are described by a new nucleation and growth multi-step model. It extends the clas…
On the magnetization process of ferromagnetic materials
R. Khachaturyan, V. Mekhitarian
The present article concludes that a ferromagnetic sample could be considered like a paramagnetic system where the role of magnetic moments plays magnetic domains. Based on this co…
