Abstract: Flexible electronic devices have attracted great interest owing to the advantages of flexible substrates as well as its arbitrary surface geometries, which may be one key branch of next-generation electronic devices, including paper-like electronic displays, light-emitting diodes, biointegrated medical devices, and solar cells. In recent years, some researchers have combined flexible techniques with spintronics to explore the effect of strain on magnetoelectric heterojunctions grown on flexible substrates and to control the magnetic and electric properties by changing the curvature of the substrate. These studies pave the path for the designing electronic devices, including magnetic storage devices, magnetic sensors, and non-volatile resistance memory.
