A electromagnetic-power-absorbing composite, comprising a binder and a plurality of multilayered flakes dispersed in the binder. The multilayered flakes include at least one layer pair comprising one thin film crystalline ferromagnetic metal layer adjacent to one thin film dielectric layer. The multilayered flakes are preferably present in an amount in the range from about 0.1% to about 10% by volume of the composite. The composite is useful for absorbing electromagnetic power having a frequency in the range from 5 to 6000 MHz so as to produce heat.
