Octahedron distortion-triggered dipole–spin interaction in multiferroic magnetoelectric perovskites

Abstract The design of perovskite structures with multiferroic magnetoelectric coupling effects opens up new opportunities in fields such as the creation next-generation spin-dependent multistate information storage technologies. In this work, we prepared a transition metal-implanted coupling, which both and blueshift photoluminescence were observed. introduction metal-generated polarized spin interacts electronic orbit through spin–orbital to lead pronounced octahedron distortion, where temperature dependence dielectric constant undergoes ferroelectric polarization transition. An external magnetic field could enhance strength further affect magnitude electric polarization. Moreover, applying an tunes distortion feed back change Overall, polarization-induced perovskites provides unique approach realizing room-temperature materials.
