It is well known that the Cr underlayer plays a critical role in generating large in-plane coercivity in Co-based magnetic thin films. In this paper we report in detail the Co-Sm (1100)//Cr (121) eptaxy revealed by high resolution electron microscopy. The lattice mismatch between Co-Sm (1100) and Cr (121) is less than 2%, suggesting an energetically favorable configuration. The high anisotropy observed in Co-Sm films is discussed by this epitaxial realtion.
