GaC MAX phase films on MgO (111) were investigated. For 12.5- to 156-nm-thick films

nm even for the thinnest films. No influence of the interface layers on the magnetic anisotropy
the magnetization or the para- to ferromagnetic phase transition was observed. All samples remained stable for more than one year in ambient conditions.
