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 co-existence 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 multi-level ferroic modulation and spin orbitronics in HOIPs are also presented. This article is protected by copyright. All rights reserved.
