Simulating the radiofrequency dielectric response of relaxor ferroelectrics: Combination of Coarse-Grained Hamiltonians and Kinetic Monte Carlo

Gregory Geneste, L. Bellaiche, Jean-Michel Kiat

The radiofrequency dielectric response of the lead-free Ba(Zr${}_{0.5}$Ti${}_{0.5}$)O${}_3$ relaxor ferroelectric is simulated using a coarse-grained Hamiltonian. This concept, taken fro…
