Abstract
A magnetic member includes a plurality of superparamagnetic particles held by the magnetic member. Each of the plurality of superparamagnetic particles is formed with a particle size which is set at least such that a Neel relaxation time τn in the each of the superparamagnetic particles becomes shorter than a cycle P of an alternating current magnetic field applied to the magnetic member (τn<P) when the magnetic member is used as an electronic component.
