Quantum Oscillations in Ferromagnetic (Sb, V)₂ Te₃ Topological Insulator Thin Films.

ABSTRACT: An effective way of manipulating 2D surface states in magnetic topological insulators may open a new route for quantum technologies based on the quantum anomalous Hall effect. The doping-dependent evolution of the electronic band structure in the topological insulator Sb_{2- x} V_x Te₃ (0 ≤ x ≤ 0.102) thin films is studied by means of electrical transport. Sb_{2- x} V_x Te₃ thin films were prepared by molecular beam epitaxy, and Shubnikov-de Hass (SdH) oscillations are observed in both the longitudinal and transverse transport channels. Doping with the 3d element, vanadium, induces long-range ferromagnetic order with enhanced SdH oscillation amplitudes. The doping effect is systematically studied in various fil
