Hall resistance at different temperatures for [MnGa (t nm)/Co2MnSi]5 superlattices. (Sample A: t = 3.75 nm, red circles; sample C: t = 5.6 nm, blue up triangles). (a) R Hall for samples A and C at two representative temperatures of 100 K (open) and 350 K (solid) in a magnetic field range from −85 to + 85 kOe. (b) Coercivity of superlattices versus temperature (H c(sl) − T) curves from 50 to 350 K.
