Thermal, magnetic, electric, and adhesive properties of amorphous Co60Fe20B20 thin films

► Kissinger's formula is used to calculate the activation energy of crystallization. ► The 3000 Å-thick of as-deposited CoFeB film forms a crystalline state easily. ► The post-annealing 150 °C and 250 °C have a good due to magneto anisotropy. ► The stronger crystallization has a lower surface energy and weaker adhesion.
