文摘
- •
Preparation and magnetic characterization of FeTaC based multilayer thin films.
- •
Effects of temperature, spacer layer and annealing on magnetization reversal.
- •
Optimum annealing recues HC largely and minimum of 0.05 Oe was obtained.
- •
Understand unusual variation of HC(T) with a broad minimum for 300 °C annealed films.
- •
Temperature dependent magnetization plays an important role in interlayer coupling.
- •
Curie temperature depends on the annealing temperature and spacer layer thickness.
