Synthesis and Comparative Structural and Magnetotransport Study of Fe₃GeTe₂ Crystals Grown by Self‐Flux and Chemical Vapor Transport Methods

The development of Fe 3 GeTe 2 and other recently introduced cleavable ferromagnets provides a foundation for constructing magnetically active 2D van der Waals heterostructures. While these architectures are primarily designed to explore their potential applications and functionalities, fundamental physical properties are important for understanding their charge and spin transport behavior. Herein, good quality single crystals of Fe 3 GeTe 2 are grown by two distinct methods, self‐flux and chemical vapor transport, and their structural and transport properties are compared. The two crystals have slight variation in stoichiometry and exhibit distinct defect density, carrier mobility, Curie temperature ( T C ), and magnetoresistance behavior. Both the crystals show anomalous Hall resistivity caused by skew scattering in the particular temperature range.
