Magnetization behavior and magnetocaloric effect in bulk amorphous Fe60Co5Zr8Mo5W2B20 alloy

► Bulk amorphous Fe60Co5Zr8Mo5W2B20 alloy is paramagnetic at room temperature. ► Curie temperature slightly increases after annealing at 720 K for 15 min. ► Alloy exhibits the second order magnetic phase transition. ► Maximum magnetic entropy changes increases after annealing. ► In the paramagnetic region the material is a Curie-Weiss paramagnet.
