摘要	The magnetic van der Waals crystals (Mn X2Te4)(m)(X2Te3)(n) (X = Sb, Bi) have drawn significant attention due to their rich topological properties and tenability by external magnetic field. In this letter, we report on the discovery of superconductivity in magnetic topological insulator candidate MnSb4Te7 (m = 1, n = 1) via the application of high pressure. The antiferromagnetic ordering is robust to pressure until 8 GPa and then fully suppressed. The carrier type converts from hole to electron accompanied with structural phase transition at similar to 16 GPa. Superconductivity emerges near the critical pressure 30 GPa where MnSb4Te7 converts to phase III. Interestingly, MnSb4Te7 shows a domelike phase diagram with a maximum T-c of 2.2 K at 50.7 GPa.
