摘要：

In this paper, Nd1-xBaxFeO3 (x = 0, 0.05, 0.10, 0.15) have been synthesized utilizing the sol-gel technique. No impurity phase was generated by XRD analysis, and all of them were solid-dissolved in the perovskite structure. Given the disparity in atomic radii between Ba2+ and Nd3+, the crystal lattice undergoes lattice distortion. The entry of Ba2+ makes NdFeO3 change from ferromagnetic to antiferromagnetic, leading to reductions in both saturation magnetization and coercivity. However, the doping of Ba2+ improves the electromagnetic properties of NdFeO3, which makes the microwave absorption properties move to low frequencies. Notably, Nd0.90Ba0.10FeO3 has better absorbing performance, the maximum reflection loss and bandwidth of it reached - 17.2 dB and 3.38 GHz, respectively. Different thicknesses can also be selected for deployment across various frequency ranges, expanding its range of potential applications.
