Ferrimagnetic Mn{sub 2}As thin films with perpendicular magnetic anisotropy were successfully grown on Si(100) by molecular-beam epitaxy. From the reflection high-energy electron diffraction and X-ray diffraction patterns, the orientation of the Mn{sub 2}As film on Si was along the c-axis in the tetragonal crystal structure. Mn{sub 2}As film exhibited ferrimagnetic ordering at temperatures greater than 300 K, which differs from antiferromagnetic or paramagnetic behaviors in the bulk form. The magnetic moment of Mn{sub 2}As determined by saturated magnetization was 0.51 {mu}{sub B} per unit cell.
