The large gyromagnetic effect (LGE) in highly positive magnetostrictive Fe77.5Si7.5B15 amorphous as-cast, furnace annealed with and without axial tension, current annealed, and transverse field annealed wires was investigated. A slight decrease in the rotation frequency of the LGE was observed in the annealed samples. Results on the influence of a localised dc bias field on the LGE of as-cast and furnace annealed samples are reported for the first time. The localised dc bias field applied along the length of the wires significantly influences both frequency and direction of the wires' rotation. (C) 2003 Elsevier B.V. All rights reserved.
