First-principles design and subsequent synthesis of a material to search for the permanent electric dipole moment of the electron

Abstract

We describe the first-principles design and subsequent synthesis of a new material with the specific functionalities required for a solid-state-based search for the permanent electric dipole moment of the electron. We show computationally that perovskite-structure europium barium titanate should exhibit the required large and pressure-dependent ferroelectric polarization, local magnetic moments, and absence of magnetic ordering even at liquid helium temperature. Subsequent synthesis and characterization of Eu${}_{0.5}$Ba${}_{0.5}$TiO${}_3$ ceramics confirm the predicted desirable properties.
