The emergence of two-dimensional (2-D) materials
provides an excellent platform for exploring and modulating exotic
physical properties in the 2-D limit, and has driven the
development of modern condensed matter physics and nanoelectronic
devices. Among various exotic physical properties, 2-D magnetism is
one of the most important topics, which shows potential application
in spintronics. In recent years, researchers have discovered a
series of intrinsic 2-D magnetic materials, such as CrI3, Fe3GeTe2,
etc. However, most of the yet discovered 2-D magnetic materials are
instable in atmosphere, which limits further investigation and the
application of 2-D magnetism. Therefore, the key issue is how to
induce magnetism in air-stable 2-D materials.
