原始语种摘要: ABSTRACT(#br)The Sr1- x Sm x Fe12- x Cu x O19 (0 ≤ x ≤ 0.2) materials were prepared by chemical co-precipitation technique. The products were characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), scanning electric microscopy (SEM) and vibrating sample magnetometer (VSM). The results of XRD showed that the pure M-type hexaferrites are obtained. The Sm3+ and Cu2+ ions were completely doped into strontium ferrite phase. With the increasing of Sm-Cu content, the grain size gradually increases. The FTIR spectra of annealed samples of Sr1- x Sm x Fe12- x Cu x O19 showed that strontium...
