Giant electrocaloric response in the prototypical Pb(Mg,Nb)O${}_3$ relaxor ferroelectric from atomistic simulations

Zhijun Jiang, Y. Nahas, S. Prokhorenko +4

An atomistic effective Hamiltonian is used to investigate electrocaloric (EC) effects of Pb(Mg${}_{1/3}$Nb${}_{2/3}$)O${}_3$ (PMN) relaxor ferroelectrics in its ergodic regime, and sub…
