Recent advances in two-dimensional intrinsic ferromagnetic materials Fe₃X(X=Ge and Ga)Te₂ and their heterostructures for spintronics

Abstract

This review summarizes the spintronic properties of Fe3X(X=Ge and Ga)Te2 and their heterostructures for spintronics, providing an overview to support further studies of emergent 2D Fe3X(X=Ge and Ga)Te2 materials and related vdWHs devices.

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

“…In particular, Fe 3 GeTe 2 is a metal distinguished by its resilience after exfoliation and exhibits a high T c with substantial strong magnetic anisotropy, , suggesting its potential for spintronics and magnonics applications. − While bulk-phase magnetism persists up to 230 K, T c is significantly reduced in thinner layers. , To address this, several strategies have been employed, such as electron gating, intercalation, − or external pressure . Among them, increasing the Fe composition in Fe x GeTe 2 crystals has proven to be a powerful method to boost the T c , reaching up to 310 K. − …”
