Abstract
Epitaxial Sm-Co(1 (1) over bar 00) and (11 (2) over bar 0) films have been grown by magnetron sputtering onto Cr(211) and (100) buffer layer s, respectively. The Sm-Co(1 (1) over bar 00) films exhibit uniaxial i n-plane anisotropies of approximate to 20-25 T and room-temperature co ercive fields that increase to 4.1 T as the film thickness decreases t o 75 Angstrom. The 3 T coercivities of the (11 (2) over bar 0) films a re independent of thickness. (C) 1997 American Institute of Physics.
