On the Origin of the Above-Room-Temperature Magnetism in the 2D van der Waals Ferromagnet Fe₃GaTe₂.

ABSTRACT: 2D magnetic materials have attracted growing interest driven by their unique properties and potential applications. However, the scarcity of systems exhibiting magnetism at room temperature has limited their practical implementation into functional devices. Here we focus on the van der Waals ferromagnet Fe₃GaTe₂, which exhibits above-room-temperature magnetism (T_c = 350-380 K) and strong perpendicular anisotropy. Through first-principles calculations, we examine the magnetic properties of Fe₃GaTe₂ and compare them with those of Fe₃GeTe₂. Our calculations unveil the microscopic mechanisms governing their magnetic behavior, emphasizing the pivotal role of ferromagnetic in-plane couplings in the stabilization
