| 1 | Radiation Losses in the Microwave X Band in Al-Cr Substituted Y-Type Hexaferrites显示文摘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. | D.Basandrai R.K.Bedi A.Dhami J.Sharma S.B.Narang K.Pubby A.K.Srivastava | 2017 | Chinese Physics Letters2017，34，4： | 0 |
