Magnetic Properties of (Fe/Co)_(83)(Sn/P)_5B_(12) RQ Ribbons

摘要

The system of FeCoSn(P)B in the ribbon form has been successfully prepared by planar flow casting on air, studied for the thermal analysis and magnetic properties. After annealing at 400 °C during two times the soft-magnetic properties result for shorter time significantly better - H_c decreased by ~ 30 %. Substitution of 2 at % P for Sn has a positive effect on the formation of stable magnetic anisotropy oriented along the ribbon axis and a slight increase in magnetic saturation (up to 1.80 T).
