Crystallization kinetics and magnetic properties of $Fe_{80-x}Co_{x}P_{14}B_6$ metallic glasses

We report about formation mechanism, crystallization kinetics and magnetic properties observed in the series of rapidly solidified $Fe_{80-x}Co_{x}P_{14}B_6$ metallic glasses with $x = 25, 32, 35$ and $40$ at.$\%$. Magnetic soft $Fe_{80-x}Co_{x}P_{14}B_6$ metallic glasses have $15$–$25$ $\mu$m thick and $2$–$8$ mm wide. The ribbon samples were created to meltspun onto the massive copper wheel from the RF-melted superheated master ingots.
