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

具有多铁磁电耦合效应的钙钛矿结构的设计为创建下一代自旋相关多态信息存储技术等领域开辟了新的机遇。在这项工作中，我们制备了一种具有多铁磁电耦合的过渡金属注入钙钛矿，其中同时观察到磁电耦合和光致发光蓝移。引入过渡金属产生的极化自旋通过自旋轨道耦合与电子轨道相互作用，导致明显的八面体畸变，其中介电常数的温度依赖性经历铁电极化转变。外部磁场可以增强自旋极化的强度，从而进一步影响电极化的幅度。而且，施加电场可调节八面体与电极化相关的畸变，以反馈自旋极化的变化。总的来说，钙钛矿中的自旋极化引起的电极化为实现多铁性材料的室温磁电耦合提供了一种独特的方法。
