The saturation magnetization and Curie temperature of residual amorphous phase,σsα and TCα were all decreased monotonically with increasing of Ta in the whole annealing process and had a linear correlation between them. The dependences of magnetic coupling between α-Fe(Si) grains and of saturation magnetostriction on volume fractions of each phase were also discussed.
