Paper Abstract

Annealing effects on magnetization behaviors of amorphous TbFeCo films have been investigated by vibrating sample magnetometer. Thermal annealing at 100 degree(s)C shows that large perpendicular anisotropy and coercivity still remain after annealing, and inverse magnetostrictive anisotropy is responsible for the decrease of coercivity. It is shown that the coercivity and anisotropy decrease greatly after annealing at temperature over 130 degree(s)C, however, long time annealing does not affect the magnetic properties of TbFeCo films evidently. Annealing at 180 degree(s)C shows that the room temperature magnetization loop in perpendicular direction is similar to that for films annealed at 130 degree(s)C, but the in- plane magnetization loop becomes strong. The remains of perpendicular anisotropy may be attributed to the pair ordering anisotropy and can not be eliminated by low temperature annealing.
