Abstract : The vast collection of two-dimensional materials and their co-integration in van der Waals (vdW) heterostructures enable innovative device engineering. Their atomically thin nature promotes the design of artificial quantum and topological materials by proximity-induced effects with physical properties not readily found in their single material forms. Such a flexible design approach is especially compelling for the development of spintronic devices, which usually harness functionalities from thin layers of magnetic and non-magnetic materials and their interfaces. In the first part of the talk I will summarize recent experimental progress toward investigating proximity-induced phenomena in hybrid graphene-transition metal dichalcogenides systems through spin transport dynamics and charge-spin interconversion experiments. In the second part, I will introduce the potential advantages of vdW heterostructures and of TIs for non-volatile spintronics memories. Particularly, I will describe the relevance of preserving the quality of the TI/FM interfaces for the generation of highly efficient spin-orbit torques and will demonstrate magnetization switching in 2D ferromagnet / TI heterostructures.
