Abstract Scalable fabrication of magnetic 2D materials and heterostructures constitutes a crucial step for scaling down current spintronic devices the development novel applications. Here, we report on van der Waals (vdW) epitaxy layered metal Fe 3 GeTe 2 (FGT)—a crystal with highly tunable properties high prospect room temperature ferromagnetism (FM)—directly graphene by employing molecular beam epitaxy. Morphological structural characterization confirmed realization large-area, continuous...
We studied metastable $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Fe}{\mathrm{Ge}}_{2}$, a layered tetragonal material, embedded as spacer layer in spin valve structures with ferromagnetic ${\mathrm{Fe}}_{3}\mathrm{Si}$ and ${\mathrm{Co}}_{2}\mathrm{Fe}\mathrm{Si}$ electrodes. For both types of electrodes, operation is demonstrated A metallic transport behavior the $\ensuremath{\alpha}\text{\ensuremath{-}}\mathrm{Fe}{\mathrm{Ge}}_{2}$ layer. The signals are found to increase temperature...
Scalable fabrication of magnetic 2D materials and heterostructures constitutes a crucial step for scaling down current spintronic devices the development novel applications. With this prospect, we have recently succeeded in growing high quality large area Fe3GeTe2 (F3GT) Fe5-xGeTe2 (F5GT) epitaxial films via molecular beam epitaxy (MBE) on graphene/SiC(0001) templates. This magnet is extremely promising such applications, given its highly tunable properties potential room temperature...
We studied metastable $α$-FeGe$_2$, a novel layered tetragonal material, embedded as spacer layer in spin valve structures with ferromagnetic Fe$_3$Si and Co$_2$FeSi electrodes. For both types of electrodes, operation is demonstrated metallic transport behavior the $α$-FeGe$_2$ layer. The signals are found to increase temperature thickness, which discussed terms decreasing magnetic coupling strength between bottom top temperature-dependent resistances exhibit characteristic features,...
