Materials that possess nontrivial topology and magnetism is known to exhibit exotic quantum phenomena such as the quantum anomalous Hall effect. Here, we fabricate a novel magnetic topological heterostructure Mn<sub>4</sub>Bi<sub>2</sub>Te<sub>7</sub>/Bi<sub>2</sub>Te<sub>3</sub> where multiple magnetic layers are inserted into the topmost quintuple layer of the original topological insulator Bi<sub>2</sub>Te<sub>3</sub>. A massive Dirac cone (DC) with a gap of 40-75 meV at 16 K is observed. By ...[more]
