Abstract
A magnetic powder is represented by general formula Fe(SiBP), and is produced with a gas atomization method. When the value of a and the value of b in the general formula is represented (a, b), (a, b) is within a predetermined region V. Similarly, (a, c) and (a, d) are within a predetermined region, respectively. Whereby, it is possible to obtain an alloy magnetic powder which has high saturation magnetic flux density, low magnetic loss, and is spherical and easy to handle; and a magnetic core, a variety of coil components, and a motor can be realized by using the magnetic material.
