High-frequency current suppression body using magnetic loss material exhibiting outstanding complex permeability characteristics
The present invention is a high-frequency current essentially of M—X—Y, where M is Fe, Co, and/or Ni, X is an element other than M or Y, and Y is F, N, and/or O. The maximum value μ″max of the loss factor μ″ of this material exists at 100 MHz to 10 GHz. A relative bandwidth bwr is not greater than 200% where the relative bandwidth bwr is obtained between two frequencies at which the value of μ″ is 50% of μ″max and normalizing the frequency bandwidth at the center frequency.
