Abstract
(100) and (111) oriented single-crystal films were deposited over a range of growth temperatures from 50 to C. The Curie temperature is increased by C over the value expected for the homogeneous alloy in the as-deposited films (of both orientations) grown near C. We interpret this as evidence for a previously unobserved, surface-mediated, magnetically driven miscibility gap in vapor-deposited films. Large perpendicular magnetic anisotropy is also observed in the as-deposited films (of both orientations) grown near C.
