Proximity-induced magnetism and spin transport in graphene/magnetic oxide heterostructure interfaces

Project description

Graphene and magnetic oxides for artificially layered heterostructures

Graphene is renowned for its exceptional electronic properties, but it is inherently characterised by weak spin-orbit coupling and a paramagnetic nature at low temperatures. With the support of the Marie Skłodowska-Curie Actions programme, the 2DMagspin project will combine graphene with transition metal magnetic oxides (graphene/MO) to create artificially layered heterostructures. This approach will enable the investigation of proximity-induced magnetism and the anomalous Hall effect in graphene, driven by high-order d-orbitals from the magnetic oxides thus enabling charge transfer-induced hybridisation. The investigation will further focus on manganate oxides and explore cobalt and magnesium-based ferrites in tandem with graphene for room-temperature applications. Ultimately, the project aims to develop novel graphene/MO-based heterostructure spin devices and assess their potential for spin transport applications.

Objective

Although graphene is known for its superlative electronic properties, it is intrinsically characterized by weak spin-orbit coupling and paramagnetic nature at low temperature. We propose to circumvent this issue by combining graphene with transition metal magnetic oxides (graphene/MO) in a unique series of artificially layered heterostructures. The presence of the magnetic oxide layer will allow us to investigate proximity induced magnetism and anomalous Hall effect (AHE) in graphene due to the presence of high order d-orbitals and ensuing charge transfer induced hybridization. To that aim, perovskite manganate oxides will be initially investigated and then extended to cobalt or magnesium-based ferrites for room temperature applicability. Finally, we aim at fabricating novel graphene/MO-based heterostructure spin devices to test their feasibility for spin transport applications.
