Research sheds insight into magnon dynamics in 2D materials
Spin is an intrinsic feature of quantum particles. Electron spins play a key role in bringing about magnetism. Their movement generates an electric current, causing each one to act like a tiny magnet. A magnon is a collective excitation of the electrons’ spin structure in a crystal lattice. In high-quality magnetic materials, magnons enable long-distance electronic spin information transfer. These collective spin excitations have extensively been studied in magnetic bulk materials and thin films. The EU-funded 2DMAGSPIN project aims to investigate magnon dynamics in 2D magnetic materials. Researchers will study electronic spin transport in two types of Van der Waals materials – atomically thin 2D layers stacked on top of each other.
Objective
Dimensionality plays a crucial role in the physical properties of condensed matter systems. In the last century, the optimization of FET technology led to the discovery of a new state of matter, in which quantum mechanics fully confines any electron motion to parallel to the interfaces, i.e. the two-dimensional electron gas (2DEG).
Magnons, the elementary excitations of the ground state magnetic order (either ferro, ferri, or antiferromagnetic) also carry spin. In high-quality magnetic materials magnons enable long-distance electronic spin information transfer. Magnonics has been studied extensively in magnetic bulk materials, or in thin films where still several sub-bands are thermally populated. The challenging major next step is to realize and study magnon and electronic spin transport in the ultimate 2D magnetic regime.
The aim of this ERC Advanced project is to combine and study strictly 2 dimensional spin transport in two types of vdW magnets: in a 2D magnon gas (2DMG) in electrically insulating Van der Waals ferro and antiferromagnets and in a 2D spin gas (2DSG) in proximity-induced magnetic graphene.
To achieve this aim, I will (i) fabricate high quality 2D vdW materials, heterostructures and devices; (ii) realize and study spin transport in a two-dimensional magnon gas (2DMG); (iii) realize and study a two-dimensional spin gas (2DSG) in magnetic graphene; and (vi) develop new spintronics functionalities in hybrid 2DMG and 2DSG heterostructures.
This project will open a regime that has not been explored before. Magnon-magnon, magnon-phonon, and magnon (electronic) spin interactions in 2D will lead to phenomena that are either difficult to realize in 3D, such as hydrodynamic spin current flow and self-oscillations, or have not yet been anticipated at all. 2DMG and 2DSG controlled by gates and, possibly, operating at room temperature will enrich the vdW spintronics and provide new strategies for information technology including heat management.
