Interfaces of magnetic thin films play a key role in determining magnetic behaviors and implementations of spintronic devices. In the last decade, the increased availability of high-quality two-dimensional (2D) materials has helped to broaden the scope of interfaces, leading to the discovery of novel electronic and magnetic properties. Here, we explore with density functional theory calculations the impact of hexagonal boron nitride (h-BN) on the magnetism and structural properties of magnetic monolayers placed on heavy metal surfaces. We found that h-BN induces various structural transitions, and we investigate how magnetic interactions, such as the Heisenberg exchange interaction and the Dzyaloshinskii-Moriya interaction (DMI), are influenced by these reconstructions. These results contribute to new avenues for stabilizing complex spin-textures.
