Abstract
We present the structural and magnetic properties of Fe2As 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 Fe2As film on Si(100) was found to be a c-axis in the tetragonal crystal structure. The tetragonal Fe2As thin film exhibited ferrimagnetic (FIM) ordering at room temperature. The magnetic moment of Fe2As was 0.1 mu(B)/unit cell determined from the saturated magnetic moment. The observed FIM in Fe2As films was attributed to the strain in the film. (c) 2009 American Institute of Physics.
