Positive and negative electrocaloric effect in BaTiO${}_3$ in the presence of defect dipoles

Yang-Bin Ma, Anna Grünebohm, Kai-Christian Meyer +2

The influence of defect dipoles on the electrocaloric effect (ECE) in acceptor doped BaTiO${}_3$ is studied by means of lattice-based Monte-Carlo simulations. A Ginzburg-Landau type…
