Abstract EN
We examined two targets containing Co40Fe40B20 and Co60Fe20B20.
We deposited Co40Fe40B20 and Co60Fe20B20 monolayer thin films of various thicknesses on glass substrates through DC magnetron sputtering; the thicknesses ranged from 25 to 200 Å.
The thermal properties of the Co40Fe40B20 and Co60Fe20B20 thin films were determined using a differential scanning calorimeter (DSC).
The thermal properties included the glass transition temperature ( T g ), onset crystallization temperature ( T x ), and glass-forming ability, which were determined according to these values.
Using the Kissinger formula revealed that the activation energy of the Co60Fe20B20 with a thickness of 75 Å is the highest, implying that crystallization was the lowest and the Co60Fe20B20 film showed anticrystallization properties.
However, the energy of 75 Å Co40Fe40B20 thin films was the lowest, which is opposite to that of Co60Fe20B20.
This observation can be reasonably explained based on the concentration of Co or Fe.
Therefore, a thickness of 75 Å is critical.
