We present the structural and magnetic properties of Fe2 As thin films grown on Si(100) by molecular beam epitaxy. From the reflection high-energy electron diffraction and x-ray diffraction patterns, the orientation of Fe2 As film on Si(100) was found to be a c -axis in the tetragonal crystal structure. The tetragonal Fe2 As thin film exhibited ferrimagnetic (FIM) ordering at room temperature. The magnetic moment of Fe2 As was 0.1 μB / unit cell determined from the saturated magnetic moment. The observed FIM in Fe2 As films was attributed to the strain in the film.
