Electronic and magnetic properties of $\alpha$-FeGe${}_2$ films embedded in vertical spin valve devices

Dietmar Czubak, Samuel Gaucher, Lars Oppermann +5

We studied metastable $\alpha$-FeGe${}_2$, a novel layered tetragonal material, embedded as a spacer layer in spin valve structures with ferromagnetic Fe${}_3$Si and Co${}_2$FeSi electrodes.…
