Abstract
Multilayer sputtering of SmFe/C(Al) plus appropriate thermal processing 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 film with structure of Ta(1000 Å)/[SmFe(40 Å)/C(Al)(5 Å)]×50/Ta(200 Å) with subsequent annealing at 650°C
