Abstract
Multilayer sputtering of SmFe/C(Al) plus appropriate thermal processin g has been used to fabricate SmFeC thin films with Al substitution for Fe. It was found that the SmFeAlC thin films exhibited exceptionally high coercivities. A coercivity of 28 kOe was realized for the thin fi lm with structure of Ta(1000 Angstrom)/[SmFe(40 Angstrom)/ C(Al)(5 Ang strom)]x50/Ta(200 Angstrom) with subsequent annealing at 650 degrees C .
