Spin-valve effect for spin-polarized surface states in topological semimetals
A single GeTe-Ni junction shows spin-valve-like magnetoresistance hysteresis at room temperature for in-plane fields, attributed by the authors to spin-dependent scattering between topological surface states of GeTe and ferromagnetic nickel.
