Abstract

First-principles calculations are conducted to compute linear magnetoelectric coupling coefficients in epitaxial (001) ${\mathrm{Sr}}0.5{\mathrm{Ba}}0.5{\mathrm{MnO}}3$ films. A large enhancement of different linear magnetoelectric elements is found in a strained-induced morphotropic phase boundary region. Such enhancement is demonstrated to originate from the behavior of the dielectric susceptibility, thanks to a simple phenomenological model that is presently shown to be relevant and accurate. This work can thus provide a promising approach towards designing highly desired single-phase multiferroic with a colossal magnetoelectric conversion.
