Abstract
The influence of furnace annealing and Joule heating on microstructure and high frequency magnetotransport properties of Fe31Co31Nb8B30 alloy has been studied using differential scanning calorimetery, hysteresis and Mössbauer spectroscopy measurements. Annealing reduces disorder in the specimens via structural relaxation improving soft magnetic properties. In as-cast specimens the spins preferentially remain within ribbon plane whereas annealing above 400 °C they become random. Magnetoimpedance shows a progressive deterioration of the magnetoimpedance response upon furnace annealing as well as Joule heating of the samples.
