To design a multiferroic material at atomic scale, strong spin-lattice and charge-lattice couplings play crucial roles. Our first-principles calculation on (SrCoO3)1/(SrTiO3)1 superlattices, with above coupling properties, yields a rich physical phase diagram as a function of epitaxial strain. In particular, a robust ferroelectric ferromagnetic insulator of Pc symmetry is stabilized at tensile strain Δa/a0 = 0.86%-5.53%. The polarization can be as large as 36 μC/cm(2) and magnetic moment can rea ...[more]
