For NdFe0.50.5Ni0.50.5O(3) synthesis, Nd(2)O3,alpha 3,-Fe2O3, and nano-NiO compounds were mixed via the solid state method. The effect of each component and that of nano-NiO on the NdFe0.50.5Ni0.50.5O(3) crystal properties was characterized by using X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), ultraviolet-visible (UV-Vis), vibrating sample magnetometer (VSM), impedance and bandgap analyses. The orthorhombic perovskite structure was confirmed by the XRD data. With the doping of nano-NiO, the unit cell volume was found to decrease. The UV-Vis spectroscopy showed that the nano-NiO-doped optical bandgap (E-g) had increased. The VSM analysis demonstrated that by doping nano-NiO to weak ferromagnetic NdFeO3, the resulting NdFe0.50.5Ni0.50.5O(3) was rendered superparamagnetic. The real and imaginary parts of dielectric permittivity (epsilon '' and epsilon '''') and the loss tangent (tan delta) characteristic of the compounds were measured at AC-signaled frequencies of 100 Hz-10 MHz and a voltage range of 0-20 V DC. The increase in active charge transmission with the doping of nano-NiO reduced the epsilon '' values. In addition, the large differences between the epsilon '' values were thought to be caused by the breakdown voltage (E-b) effect of the compounds. The epsilon '''' and tan delta changes revealed the dipole formation of the compounds at different voltages, their relaxation regions and their polarization mechanism type. The dielectric loss behavior of the compounds demonstrated their good dielectric material properties. This study investigated the effect of method difference and doped material particle size on magnetic and dielectric properties.en10.1142/S0218625X24500458info:eu-repo/semantics/closedAccessNdFeO3magnetic propertiesimpedance analysisorthoferrite nano-nickel oxideperovskiteNanoparticles SynthesisHematiteCrystalsArticle3162-s2.0-85179108658WOS:001120592200001Q3Q4
