Abstract
An Fe-based soft magnetic alloy essentially consisting of an Fe-based alloy including fine crystal grains used for such as a magnetic core. An average size of the fine crystal grains is controlled to 300 .ANG. or less. Each of the fine crystal grains is composed of a body-centered cubic phase at least partially including a super lattice. This alloy has a high saturation flux density and excellent soft magnetic characteristics such as a low iron loss and a high magnetic permeability.
