文摘
- •
We study structure and temperature dependent magnetic properties of laminated films.
- •
Optimum annealing reduces HC by three orders and minimum of 0.02 Oe was obtained.
- •
Multistep magnetization reversal exhibits strong depends on x, TA and T.
- •
Interlayer coupling changes the magnetization reversal behavior substantially.
- •
Unusual HC(T) caused by interlayer coupling was observed for 300 °C annealed films.
- •
Curie temperature of the laminated films strongly (significantly) vary with TA(x).
