MAGNETIC MATERIAL FOR HIGH FREQUENCY APPLICATIONS AND HIGH FREQUENCY DEVICE

摘要

Disclosed is a magnetic material for high frequency applications, which has achieved a lower loss. Specifically disclosed is a magnetic material for high frequency applications, which is obtained by dispersing magnetic particles in a resin material. The magnetic particles have a generally spherical shape, and the resin material contains the magnetic particles in an amount of 1-60 vol%. The magnetic particles have a saturation magnetic flux density of not less than 1 tesla, and the magnetic anisotropy constant of the magnetic particles satisfies K1 3 (J/m3) in cases when the magnetic particles are composed of a cubic system material and satisfies Ku 3 (J/m3) in cases when the magnetic particles are composed of a uniaxially anisotropic material.
