Two-dimensional (2D) van der Waals magnets have emerged as an exciting area of research, providing unique opportunities to study magnetism in reduced dimensions. Among these materials, Fe3GaTe2 is particularly notable for its exceptionally high Curie temperature [1], which enables investigations and device applications at room temperature. Moreover, its structural and compositional similarity to Fe3GeTe2, one of the most extensively studied 2D magnets, suggests significant potential for tuning its magnetic properties [2,3], making it a promising candidate for both fundamental research and spintronic device applications. In this study, we explore the spin texture stability of Fe3GaTe2 thin flakes, prepared through mechanical exfoliation, using magnetic force microscopy (MFM). We also assess their resistance to oxidation [4] and degradation under ambient conditions, confirming their robust performance. These results highlight Fe3GaTe2 as a high-TC, stable 2D magnet, well-suited to advancing research in 2D magnetism and enabling next-generation spintronic technologies. References: [1] H.
