Abstract
The energetic and magnetic properties of wurtzite GaN/MnxGa1−xN digital heterostructures are investigated by first‐principles total energy calculations, within the spin density functional theory, and Monte Carlo simulations. At 700°C, up to the concentration of 8% Mn, the 2D alloy is stable. However, above this concentration, there is a strong tendency to the formation of MnN clusters with an AFM ground state defined by ferromagnetic Mn rows coupled antiferromagnetically with other Mn rows. The behavior of the magnetization with temperature is completely different in these two concentration regimes, with the 2D MnN‐cluster being very stable, whereas the 2D alloy presents low magnetic transition temperatures.
