We report on the electromagnetic (EM) properties in high-frequency domain (HF) of multiferroic Bi2FeCrO6 (BFCO) thin films. The films were epitaxially grown on SrTiO3 substrates by pulsed laser ablation. Typical 50 nm-thick BFCO films having both (111) and (001) orientations were investigated. The films exhibit systematically deep EM absorbance narrow bands, localized in the HF X-band domain, with an attenuation reaching as high as-24 dB. The magnitude and the shape of EM absorption depend on the crystal orientation of the film. BFCO thin films show a promising potential for microwave application as specific frequency bands notch filters.
