Abstract: pintronic systems, where spin replaces charge, are known for their high speed and low power consumption. Magnetic random access memory（MRAM）, a typical spintronic system, is seen as one of the best candidates of next-generation memory devices. In the field of Spintronics, two-dimensional（2D） materials are of increasing attention due to the high-quality surfaces, the scales approaching the scaling limit and the unique physical properties induced by their 2D structure. In this article, we outline the recent advances in spintronic systems based on 2D materials. First, we introduce some 2D magnetic materials and their common properties. Next, we discuss several main spintronic devices and representative works. Then we come to the modulation of magnetism based on 2D materials. Finally, we provide a brief summary of the whole article and an outlook for future development.
