  Magnetic two-dimensional (2D) materials have received tremendous attention
recently due to its potential application in spintronics and other magnetism
related fields. To our knowledge, five kinds of 2D materials with intrinsic
magnetism have been synthesized in experiment. They are CrI3, Cr2Ge2Te6, FePS3,
Fe3GeTe2 and VSe2. Apart from the above intrinsic magnetic 2D materials, many
strategies have also been proposed to induce magnetism in normal 2D materials
such as atomic modification, spin valve and proximity effect. Various devices
have also been designed to fulfill the basic functions of spintronics: inducing
spin, manipulating spin and detecting spin.
