Critical temperatures of two dimensional magnets beyond linear spin wave theory: application to CrI, MPS (M=Ni, Mn, Fe) and CrSBr
Varun Rajeev Pavizhakumari, Thomas Olsen
Magnetic anisotropy is crucial for sustaining long range magnetic order in two-dimensional materials (2D) and must be taken into account by any approximate scheme for calculating c…

Predicting the Néel temperatures in general helimagnetic materials: a comparison between mean field theory, random phase approximation, renormalized spin wave theory and classical Monte Carlo simulations
Varun Rajeev Pavizhakumari, Thomas Olsen
The critical temperature for magnetic order comprises a crucial property of any magnetic material and ranges from a few Kelvin in certain antiferromagnets to 1400 K in ferromagneti…
