Two-dimensional magnets are a key resource for next-generation spintronic and topological electronic devices. Many of them exhibit topological magnon spectra and host skyrmions providing thus a low energy alternative for classical information processing.  Most of the novel 2D materials are challenging to study because of their dimensionality, geometry and chemical composition. Within this research project the PhD student will acquire the use of  suitable first principles methods, such as SIESTA or Quantum Expresso, and devise effective magnetic model parameters suitable to calculate magnon spectra and to perform large-scale spin dynamics simulations. Particular attention will be paid to the calculation of tensorial exchange interactions including anisotropies and the Dzyaloshinsky-Moriya interaction that makes possible to study chiral magnetic phenomena on ab initio level. Moreover, by using a Green’s function perturbation approach, we will attempt to calculate fourth-order spin-interactions proposed to play an important role in stabilizing complex non-collinear magnetic structures like magnetic skyrmions. Our aim is to study novel magnetic phenomena such as two-dimensional ferromagnetism, Weyl magnons in antiferromagnetic insulators and in 2D van der Waals heterostuctures. One of the major objectives of the research is to understand how key properties of novel two-dimensional van der Waals magnets can be predicted to unlock their potential for applications as an MRAM device. The research will be performed in collaboration with the groups of László Oroszlány (ELTE) and Prof. Jaime Ferrer (Oviedo University, Spain).
