Multiferroic perovskite oxides with ferromagnetic and ferroelectric ordering simultaneously are being extensively sought for a potential linear magnetoelectric coupling effect – ferroelectric polarization switched by magnetic field and magnetization reversed by electric field, which are promising for nonvolatile high‐density electric‐writing/magnetic reading memory and spintronic applications. Using the reliable extant data of perovskite oxides, physics‐guided data‐mining is carried out to unveil the room temperature multiferroic chemistry. Double perovskite oxides with rocksalt‐type d 5 –d 3 network on the B‐site are mined out to be promising multiferroic compounds with parallel ferroelectric polarization and magnetization. In the selective chemical space, BiFeO 3 –BiCrO 3 –PbTiO 3 ternary solid solution within some range of composition in double‐perovskite structure is designed with the assistance of domain knowledge and demonstrated experimentally to be ferrimagnetic and ferroelectric with both Curie temperatures above 300 K. Suitable synthesis method for processing highly resistive ceramic samples is necessarily required for electrical switching characterizations and device applications. Physics‐guided data‐mining driven material design is illustrated to be an efficient approach to accelerate the discovery of novel multiferroic crystals.
