CoFeMn0.5Al0.25: a high magnetisation CoFe based soft alloy with reduced Co content

Abstract

The high cost of CoFe alloys has prevented their widespread use regardless of their promising properties such as high magnetisation, high Curie temperature, as soft magnetic materials for high temperature applications. Here, it is shown that AlMn can be used to create a CoFeMn0.5Alx alloy, which has reduced Co content but comparable soft magnetic properties as CoFe alloys, therefore providing a more economical alternative to pure CoFe soft magnets.
