Abstract

A new family of Fe-Co based high temperature nanocrystalline alloy was developed using Fe85-xCoxNb5B8P 2 as a precursor amorphous material, which can be cast in air. The nanocrystalline sample presented a flat hysteresis loop with excellent high frequency and high temperature behaviour. The material crystallizes at relative low temperature (400°C), with a relatively low activation energy (2.7eV) for x=20. The sample annealed at 500°C shows temperature independent soft magnetic properties (Hc around 40A/m, relative permeability 450 up to 1MHz) up to the applied annealing temperature.
