The van der Waals (vdW) ferromagnet compared to conventional ferromagnetic materials provides a unique configuration of magnetic interactions due to its quasi two-dimensional (2D) nature. The pair-exchange interaction is mainly established within the 2D plane, while magnetic coupling between interlayers is weak. Therefore, the vdW ferromagnets are ideal for 2D spintronic devices that show various emergent spin-orbit coupled phenomena with time reversal and inversion symmetry breaking.
As a promising vdW ferromagnet, the Fe<sub>n</sub>GeTe<sub>2</sub> family (n = 3, 4, 5) was proposed based on its high T<sub>C</sub> (260 ~ 310 K) and large saturation magnetization. Recently, the unconventional magnetic properties of Fe<sub>5</sub>GeTe<sub>2</sub> have been explained with magnetic anisotropy or/and spin reorientation by the Fe atoms in Fe<sub>5</sub>GeTe<sub>2</sub>. However, the exact mechanism of such non-trivial magnetic behaviors is still unclear because it is also involved with the structural complexity in Fe<sub>5</sub>GeTe<sub>2</sub>. Therefore, systematic study for finding the correlation between such non-trivial magnetic behaviors and the atomistic structure of Fe<sub>5</sub>GeTe<sub>2</sub> is needed to realize room temperature spintronic devices with this new vdW ferromagnet.
