High Curie temperature ferromagnetic structures of (Sb₂Te₃)_1-x(MnSb₂Te₄)_x with x = 0.7-0.8.

ABSTRACT: Magnetic topological materials are promising for realizing novel quantum physical phenomena. Among these, bulk Mn-rich MnSb₂Te₄ is ferromagnetic due to Mn_Sb antisites and has relatively high Curie temperatures (T_C), which is attractive for technological applications. We have previously reported the growth of materials with the formula (Sb₂Te₃)_1-x(MnSb₂Te₄)_x, where x varies between 0 and 1. Here we report on their magnetic and transport properties. We show that the samples are divided into three groups based on the value of x (or the percent septuple layers within the crystals) and their corresponding T_C values. Samples that contain x < 0.7 or x > 0.9 have a single T
