摘要：

We report a proximity-driven large anomalous Hall effect in all-telluride heterostructures consisting of the ferromagnetic insulator Cr2Ge2Te6 and topological insulator (Bi, Sb)(2)Te-3. Despite small magnetization in the (Bi, Sb)(2)Te-3 layer, the anomalous Hall conductivity reaches a large value of 0.2e(2)/h in accord with a ferromagnetic response of the Cr2Ge2Te6. The results show that the exchange coupling between the surface state of the topological insulator and the proximitized Cr(2)Ge(2)Te(6 )layer is effective and strong enough to open the sizable exchange gap in the surface state.
