摘要:

采用柠檬酸-硝酸盐自燃多孔产物在1473 K下热处理制备了SrFe 8Al 4 O 19单畴颗粒,研究了合成时间对颗粒形貌和磁性能的影响。该过程允许获得平均直径为100 - 460 nm的SrFe_8Al_4 O_(19)颗粒,并且它们的矫顽力范围为14.5 - 18.4 kOe,而铁磁共振频率范围为149 - 164 GHz。

英文摘要:

Single-domain particles of SrFe8Al4O19 were prepared by thermal treatment at 1473 K of porous products of citrate-nitrate auto-combustion, and the influence of synthesis time on the particle morphology and magnetic properties was studied. The procedure allows to obtain SrFe8Al4O19 particles with mean diameters 100 - 460 nm, and their coercivity ranges from 14.5 to 18.4 kOe, while ferromagnetic resonance frequencies vary from 149 to 164 GHz.
