A delicate superlattice structure of Cr2Te3/Bi-2/Bi2Te3 has been constructed based on the chemical reduction at the interface. The growth was conducted by molecular beam epitaxy, and the structural characterizations have provided solid evidence of the designed structure. The interfaces between Cr2Te3, Bi-2, and Bi2Te3 are sharp, and ferromagnetism has been introduced in this system as revealed by the negative magnetoresistance curve and the anomalous Hall effect.
