Topologi cal insulators are characterized by symmetry-protected gapless boundary st ates. Particularly interesting are three-dimensional topological insulator s\, whose electromagnetic response features a topological magnetoelectric effect\, which is closely related to the so-called chiral     anomaly in relativistic quantum field theories. In the context of solid state phy sics the chiral anomaly arises as a second-quantized version of the Berry phase induced by the electromagnetic response of   topological insulato rs. This property plays an important role in heterostructures involving bo th topological insulators and magnetic materials. In this talk we will con sider theoretical and experimental aspects of bilayer and trilayer structu res of the form FM/TI and FM/TI/FM (FM=Ferromagnet\, TI=Topological Insula tor) using a quantum-field theoretic approach. The paradigmatic experiment al example to be discussed is one in which FM=EuS and TI=Bi2Se3.
