The structural and magnetic properties of Sm{sub 21}Fe{sub 10}Co{sub 7}/M{sub x}C{sub y} (M = Al and Si; x {ge} 0 and y {le} 0) multilayer films with Ta underlayers and overlayers before and after annealing at 700 C for 5--12 min have been fabricated and studied. Structural studies show evidence of layer diffusion upon annealing, X-ray diffraction shows that the samples after annealing consist of a soft phase, {alpha}-Fe, and a hard phase with the 2--17-type structure. The samples studied have in-plane anisotropy with single hysteresis loops indicating that the two phases are strongly exchange coupled. After annealing, the coercivity of samples with Al{sub x}C{sub y} is found to increase with increasing Al{sub x}C{sub y} composition to a maximum of 3.3 kOe. The energy products for these samples are found to increase from 1.4 MGOe for SmFeCo to 8 MGOe for SmFeCo with Al{sub x}C{sub y}.
