    Research of FY 2024 focused on the langasite materials showing helical magnetism. The Heisenberg Hamiltonian parameters of the four iron based materials Ba3NbFe3Si2O14, Sr3NbFe3Si2O14, Ba3SbFe3Si2O14 and Ba3TaFe3Si2O14 were determined with DFT energy mapping. We analyzed the resulting Hamiltonians for classical spins with iterative minimization and classical Monte Carlo techniques. The results are very encouraging, with helical order predicted correctly. A publication is in preparation.
    In parallel, we investigated the evolution of the electronic and magnetic properties of the van der Waals ferromagnet CrGeTe3 under pressure; in particular, we explored the anomalous Hall effect (AHE) in CrGeTe3. It can be observed as soon as the pressure induced insulator to metal transition occurs. While our theoretical calculations predict a sign change in the anomalous Hall conductivity due to intrinsic Berry curvature effects, experimental observations show only an enhancement followed by a decay of the AHE under pressure. This leads us to conclude that the AHE is primarily driven by extrinsic mechanisms. We outline potential scenarios for these extrinsic contributions and their role in the anomalous Hall conductivity.
