The first few-layered van der Waals magnetism was reported in 2017 (Cr 2 Ge 2 Te 6, and CrI 3). One reason for this seemingly late discovery is that thermal fluctuations tend to destroy magnetic order for 2D magnets more easily compared to 3D bulk. It is also generally accepted in the community that low dimensional materials have different magnetic properties compared to bulk. This academic interest that transition from 3D to 2D magnetism can be measured has been the driving force behind much of the recent works on van der Waals magnets. Much anticipated transition of such has been since observed in both antiferromagnets and ferromagnets: FePS 3, Cr 2 Ge 2 Te 6, CrI 3, NiPS 3, MnPS 3, Fe 3 GeTe 2
