Low-field magnetic properties of wide Fe-Ni metallic glass strips

Abstract
Wide samples of continuous-cast metallic glass ribbons fabricated to tape-wound or punched-ring core configurations are shown to possess the same attractive low-field magnetic properties as are observed in narrow ribbons of similar composition. Annealing ring-laminated cores in crossed fields leads to lower core loss than for metallic glass (wide or narrow) annealed only in a circumferential field.
