Title: A magnetic atomic laminate from thin film synthesis: (Mo{sub 0.5}Mn{sub 0.5}){sub 2}GaC

We present synthesis and characterization of a new magnetic atomic laminate: (Mo{sub 0.5}Mn{sub 0.5}){sub 2}GaC. High quality crystalline films were synthesized on MgO(111) substrates at a temperature of ∼530 °C. The films display a magnetic response, evaluated by vibrating sample magnetometry, in a temperature range 3-300 K and in a field up to 5 T. The response ranges from ferromagnetic to paramagnetic with change in temperature, with an acquired 5T-moment and remanent moment at 3 K of 0.66 and 0.35 μ{sub B} per metal atom (Mo and Mn), respectively. The remanent moment and the coercive field (0.06 T) exceed all values reported to date for the family of magnetic laminates based on so called MAX phases.
