The Co-modified Finemet and Nanoperm type alloys were subjected to thermo-magnetic treatment and an effect of temperature and magnetising field frequency on their soft magnetic properties was investigated. It was found that Finemet type alloys containing 40 at.% Co and the FeCoNbP Nanoperm type alloy exhibit good stability of their magnetic properties at elevated temperatures, whereas properties of Finemet modified with 58.8 at.% Co are the least stable. Magnetic permeability of the investigated alloys was ranging from 1000 to 5000, making them particularly suitable for application as magnetic components in power electronics.
