Perovskite multiferroics have drawn significant attention in the development of next-generation multifunctional electronic devices. However, majority existing exhibit ferroelectric and ferromagnetic orderings only at low temperatures. Although interface engineering complex oxide thin films has triggered many exotic room-temperature functionalities, desired coupling charge, spin, orbital lattice degrees freedom often imposes stringent requirements on deposition conditions, layer thickness...
