This chapter deals with advancement in sustainable perovskite multiferroics materials, and their application in spintronics devices. Multiferroics materials are the materials which possess more than one ferroic properties namely ferroelectricity, ferromagnetism, and ferro-elasticity. The design and synthesis of perovskite multiferroics can be done using green chemistry approaches. This chapter also include characterization techniques for the study of structural, magnetic, electric as well as coupling phenomenon in this material. A brief review is also given on prominent applications including spintronic memory devices, logic devices, spin–orbit torque devices, sensors, and actuators. The challenges and limitations for sustainable perovskite multiferroic material development and practical integration are also discussed.
