• BiFe 1−x Y x O 3 ( x  = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) ceramics were synthesized by modified thermal treatment method. The structural, magnetic, and microwave absorption properties of the samples were studied by X-ray diffraction (XRD), field emission scanning electron microscopy, vibrating sample magnetometer (VSM), and professional network analyzer. XRD analysis indicates the phase transformation has occurred from rhombohedral R3c ( x  = 0.0–0.1) to orthorhombic Pnma ( x  = 0.2–0.4), and to cubic Fm-3 m ( x  = 0.5). With the increase of Y-concentrations, the average grain size was decreased from 354 to 90 nm. VSM analysis indicates the saturation magnetization, M s and remnant magnetization, M r at x  = 0.2 was enhanced about 3.95 emu/g and 1.21 emu/g. The microwave measurements at 1 mm thickness over 8–12 GHz demonstrate that the highest absorption properties has occurred at x  = 0.0 with a minimum value of reflection loss of about − 5.25 dB.
