Excellent Bidirectional Adjustable Multistage Resistive Switching Memory in BiFeCrO Thin Film.

As an important method to further improve the storage density of resistive memory, multistage resistive switching devices have become an important research direction. However, no stable and controllable multistage resistive switching device has been prepared, and the working mechanism is still unclear. Here, a sandwich-structured device is simply prepared by spin coating, with the work layer is the BiFeCrO thin film.
