MAGNETIC BODY AND ELECTRONIC COMPONENT COMPRISING THE SAME

摘要

In an embodiment, a magnetic body includes soft magnetic alloy grains 11 containing Fe, element L, and element M (where element L is Si or Zr and element M is a metal element other than Si or Zr that oxidizes more easily than Fe), as well as oxide film produced from oxidization of part of these grains 11; wherein at least some of the bonds between adjacent soft magnetic alloy grains 11 are by way of the oxide film; the oxide film has an inner film 12a, and an outer film 12b positioned on the outer side of the inner film 12a; and the inner film 12a contains more of element L than element M, while the outer film 12b contains more of element M than element L.

主权项

1. A magnetic body comprising:
soft magnetic alloy grains containing Fe, element L, and element M where element L is Si or Zr and element M is a metal element other than Si or Zr that oxidizes more easily than Fe, as well as oxide film produced from oxidization of part of the soft magnetic alloy grains; wherein adjacent soft magnetic alloy grains are bonded at least partly by the oxide film; the oxide film has an inner film, and an outer film located on an outer side of the inner film; and the inner film contains more of element L than element M, and the outer film contains more of element M than element L.
