Anomalous change in leakage and displacement currents after electrical poling on lead-free ferroelectric ceramics
Hitesh Borkar, M. Tomar, Vinay Gupta +2
We report the polarization, displacement current and leakage current behavior of a trivalent nonpolar cation Al cation substituted lead free ferroelectric NBT-BT electroceramics wi…
Electron-Beam Driven Relaxation Oscillations in Ferroelectric Nanodisks
Nathaniel Ng, Rajeev Ahluwalia, Ashok Kumar +3
Using a combination of computational simulations, atomic-scale resolution imaging and phenomenological modelling, we examine the underlying mechanism for nanodomain restructuring i…
Ferroelectric Capped Magnetization in Multiferroic PZT/LSMO Tunnel Junctions
Ashok Kumar, D. Barrionuevo, N Ortega +4
Self-poled ultra-thin ferroelectric PbZr0.52Ti0.48O3 (PZT) (5 and 7 nm) films have been grown by pulsed laser deposition technique on ferromagnetic La0.67Sr0.33MnO3 (LSMO) (30 nm)…
