“…The physical mechanisms behind the interplay of these materials’ multiple physical effects have led to unprecedented advances in understanding their properties and have provided immense benefits to modern multifunctional devices and niche applications. Successful applications, especially in recent years, range from energy conversion devices, − sensors, − and memory elements − to energy-efficient microelectronics . To make materials smart for flexible electronics, many efforts have been made to fabricate various ferroelectric and ferromagnetic heterostructures and novel topological oxides that exhibit these properties. − Similar to ferroelectric oxide materials, HOIFs have attracted much attention due to the increase in their structural degrees of freedom that result judiciously from the mediation of organic cations, providing diversified architectures and flexible frameworks that allow structural distortions that are otherwise forbidden in standard inorganic structures .…”
