Magnetic properties and microwave absorption in Ni-Zn and Mn-Zn ferrite nanoparticles synthesized by low-temperature solid-state reaction

▶ In this work, the band width (BW) of 2.3 GHz was obtained with reflection loss/written-loss (RL) of −16 dB around 10.4 GHz for Ni0.7Zn0.3Fe2O4 nanoparticles. ▶ Our results, with and without atmosphere control, are in good agreement with previous studies, which performed the experiment in the presence of argon atmosphere control. ▶ According to our experimental observation, for Ni0.7Zn0.3Fe2O4 nanoparticles, the compound of 60% ferrite with 40% resin has an optimum microwave absorption. ▶ In this work, Mn0.7Zn0.3Fe2O4 and Ni0.7Zn0.3Fe2O4 nanoparticles were produced at room temperature.
