Magnetic Anisotropy in (Cr0.5Mn0.5)2GaC MAX Phase

Magnetic MAX phase (Cr0.5Mn0.5)2GaC thin films grown epitaxially on a MgO(111) substrates were studied by ferromagnetic resonance (FMR) at temperatures between 110 K and 300 K. The spectroscopic splitting factor g = 2.00 ± 0.01 measured at all temperatures indicates pure spin magnetism in the sample. At all temperatures we find the magnetocrystalline anisotropy energy to be negligible which is in agreement with the identified pure spin magnetism.
