Ferroics in Hybrid Organic-Inorganic Perovskites: Fundamentals, Design Strategies, and Implementation

Hybrid organic-inorganic perovskites (HOIPs) afford highly versatile structure design and lattice dimensionalities; thus, they are actively researched as material platforms for the tailoring of ferroic behaviors. Unlike single-phase organic or inorganic materials, the interlayer coupling between organic and inorganic components in HOIPs allows the modification of strain and symmetry by chirality transfer or lattice distortion, thereby enabling the coexistence of ferroic orders. This review focuses on the principles for engineering one or multiple ferroic orders in HOIPs, and the conditions for achieving multiferroicity and magnetoelectric properties. The prospects of multilevel ferroic modulation, chiral spin textures, and spin orbitronics in HOIPs are also presented. Hybrid organic-inorganic perovskites are emerging as novel material paradigms with intrinsic ferroic behaviors. This review summarizes the fundamentals and design strategies of ferroelectricity, ferroelasticity, and ferromagnetism in hybrid organic-inorganic perovskites, and also discusses the underlying mechanisms of their multiferroic and magnetoelectric properties. The potential implementation in multilevel ferroic modulation, chirality as well as spin orbitronics is also presented.image
