In this work, SrBaPbFeO/(CuFe₂O₄) (x = 2, 3, 4, and 5) as strongly exchange-coupled nanosized ferrites were fabricated using a one-pot sol⁻gel combustion method (citrate sol-gel method). The X-ray diffraction (XRD) powder patterns of the products confirmed the occurrence of pure, exchange-coupled ferrites. Frequency dependencies of the microwave characteristics (MW) were investigated using a co-axial method. The non-linear behavior of the MW with the composition transformation may be due to different degrees of Fe ion oxidation on the spinel/hexaferrite grain boundaries and strong exchange coupling during the hard and soft phases.
在本工作中，采用一锅溶胶-凝胶燃烧法（柠檬酸盐溶胶-凝胶法）制备了SrBaPbFeO/(CuFe₂O₄)（x = 2、3、4和5）作为强交换耦合纳米铁氧体。产物的X射线衍射（XRD）粉末图谱证实了纯的、交换耦合铁氧体的生成。使用同轴法研究了微波特性（MW）的频率依赖性。微波随成分转变的非线性行为可能归因于尖晶石/六方铁氧体晶界上Fe离子氧化程度的不同以及硬相和软相期间的强交换耦合。
