It is an \u003c\/span\u003e\u003cstrong\u003eitinerant two-dimensional ferromagnet\u003c\/strong\u003e\u003cspan\u003e with strong perpendicular anisotropy, whose Curie temperature (~150–230 K) and magnetic properties are highly sensitive to the Fe vacancy concentration x. This tunability, combined with gate- and intercalation-driven control of T_c toward room temperature, makes Fe₃₋ₓGeTe₂ a key model system for studying \u003c\/span\u003e\u003cstrong\u003eitinerant magnetism, heavy-fermion-like behavior, and two-dimensional spintronics\u003c\/strong\u003e\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e","brand":"2D Material Supermarket","offers":[{"title":"Default Title","offer_id":53906276876472,"sku":null,"price":6503.0,"currency_code":"CNY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0649\/0069\/4200\/files\/91f5a4b89f1b1ba558eefc49f65fe22e_c362efa5-807c-43ad-bed3-8026d00d14b1.jpg?v=1786624984","url":"https:\/\/2dmaterialsupermarket.com\/products\/fe-%e2%82%93gete-1","provider":"2D Material Supermarket","version":"1.0","type":"link"}
