We report the structure, magnetic and transport properties of CoFeMnSi equiatomic quaternary Heusler alloy thin films. The epitaxial growth of the CFMS thin films with L2₁ or higher Y-type ordered structure on MgO (001) substrate was achieved using the in situ postannealing at temperature of 500℃. A saturation magnetization value of about 830 emu/cc was obtained at room temperature. The electrical conductivity measured at 300K is about 6150 S/cm.
