Investigation of glass forming ability, thermal stability and soft magnetic properties of melt-spun Fe83P16 − x Si x Cu1 (x =0, 1, 2, 3, 4, 5) alloy ribbons.

Highlights: [•] The addition of Si improves the controllability of annealing process effectively. [•] The addition of Si decreases the annealing temperature sensitivity of Hc. [•] The Hc of nanocrystalline alloys decreases with the addition of Si. [ABSTRACT FROM AUTHOR]
