Author(s): Zhijun Jiang, Sergei Prokhorenko, Sergey Prosandeev, Y. Nahas, D. Wang, Jorge Íñiguez, E. Defay, and L. Bellaiche Atomistic effective Hamiltonian simulations are used to investigate electrocaloric (EC) effects in the lead-free Ba ( Zr 0.5 Ti 0.5 ) O 3 (BZT) relaxor ferroelectric. We find that the EC coefficient varies nonmonotonically with the field at any temperature, presenting a maximum that can be traced back to th... [Phys. Rev. B 96, 014114] Published Mon Jul 24, 2017
