摘要: The magnetic properties of hexagonal (Mo0.5Mn0.5)2GaC MAX phase synthesized as epitaxial films on MgO (111) substrates with the c-axis perpendicular to film plane are presented. analysis temperature-dependent ferromagnetic resonance (FMR) and magnetometry data reveals a ferro- paramagnetic transition at 220 K. electrical transport measurements 5 K show negative magnetoresistance 6% in field 9 T. Further confirms spin-dependent scattering charge carriers this layered material. A small (c-axis) magnetocrystalline anisotropy energy density (MAE) 4.5 kJ/m3 100 K was found using FMR. Accordingly, behaves similar (Cr0.5Mn0.5)2GaC soft functional theory calculations reveal that sign amplitude MAE can be very sensitive lattice parameters, which may explain measured properties.
