Non-collinear magnetism has emerged as a fundamental and experimentally intriguing aspect of magnetism as one of the most non trivial aspects because of novel topological spin textures (skyrmions) and its potential applications in spintronic devices. Experiments on Mn2RhSn have reported an unusual ground state with magnetic canting and a temperature-induced transition into the collinear ferrimagnetic mode.
In this work, we employ first-principles calculations to implement a mean-field approximation of the ground state in Mn2RhSn and Mn2IrSn compounds. This computational approach aims to provide deeper insights into exchange interactions and the magnetic orientation behaviour observed in the experiments.
