Spin Transport Proximity Phenomena in Van der Waals Heterostructures

The vast collection of two-dimensional materials and their co-integration in van der Waals 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 [1]. 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 this talk, I will summarize recent experimental progress toward investigating proximity-induced phenomena in hybrid graphene-transition metal dichalcogenides systems through spin transport dynamics [2,3] and charge-spin interconversion experiments [4]. I will focus on the relevance of crystal symmetries in the emergence of unconventional charge-spin conversion components and anisotropic spin dynamics [5], [6].<br/><br/>References<br/>[1] J.F.
