Abstract We present a study on radiation losses in the microwave X band in Al-Cr substituted Y-type hexaferrites, namely Ba$_2$Mg$_2$Al$_{x/2}$Cr$_{x/2}$Fe$_{12-x}$O$_{22}$ ($x=0$, 0.5 and 1.0). The study is performed by means of a vector network analyzer, Fourier transform infrared spectroscopy, a vibrating sample magnetometer and x-ray powder diffraction. Ba$_2$Mg$_2$Fe$_{12}$O$_{22}$ hexaferrite shows radiation loss of $-$37.25 dB (99.999% loss) at frequency 9.81 GHz, which can be attributed to its high value of saturation magnetization, i.e., 22.08 emu/g. Moreover, we obtain that magnetic properties have strong influence on the radiation losses.
