From: High Curie temperature ferromagnetic structures of (Sb2Te3)1−x(MnSb2Te4)x with x = 0.7–0.8
Structural characteristics of the (Sb2Te3)1−x(MnSb2Te4)x samples that may lead to two TC components. (a) Illustration of the layers of samples from the three groups defined in Fig. 1a, QLs and SLs are marked in blue and green respectively. In the sample representing group 2 (75%SLs) a dashed red square and a dashed blue square indicate the regions that lead to TC1 and TC2, respectively. (b) Temperature dependent Hall resistance (Rxy) plot of a sample containing 75% SLs taken at 0.02 T. Shaded red and blue areas under the plot signify the proposed contribution for the TC1 and TC2 components. Inset: Rxy as a function of the magnetic field, B, measured at 10 K and 75 K.
