dc.description.abstract | The technological applicability of FeCoNbBCu alloys is suggested in terms of measurements of room temperature magnetoimpedance and temperature dependence of magnetic permeability m r . Results for the Fe 78- x Co x Nb 6 B 15 Cu 1 alloy series show that room temperature soft magnetic properties are enhanced in the lowest Co containing alloy ( m r ; 10 500 and magnetoimpedance ratio ; 60% at 1 MHz ! . However, permeability exhibits a smoother thermal dependence in the alloys with medium and high Co content. A tradeoff between magnetic softness and its thermal stability reveals the alloy with 39 at. % Co as the most suitable composition among those studied, characterized by a temperature coefficient of ; 0.02%/K from room temperature up to 900 K. This value is 1 order of magnitude smaller than those observed for FeSiBCuNb ~ FINEMET-type ! alloys and Mn ferrites and extended over a much wider temperature range than in these materials. | es |
