“…The rare earth element, samarium has been used due to their larger ionic radii and it effects the transport properties of the material [12]. The other rare earth elements like cerium belongs to lighter rare earth elements (1.02Å) and dysprosium belongs to heavier rare earth elements (1.03Å) have smaller ionic radii as compared to samarium (1.07Å).…”

Spinel ferrites nanoparticles have attracted the attention of researcher for memory storage devices. We have synthesized MgFeO4 pure sample and MgFe1.8Sm0.2O4 doped sample via solgel technique. The study of structural, electrical, dielectric, and I-V properties were studied of synthesized spinel magnesium ferrites nanoparticles. X-ray diffraction (XRD) confirmed the spinel structure of both compositions. The frequency dependent AC conductivity, dielectric constant, dielectric tangent loss, was studied in the range of 20Hz to 3MHz. I-V measurements has been done for the resistive switching properties. I-V curves of both compositions in the current study exhibits the formation of hysteresis loop. The hysteresis loop behavior shows that with the addition of samarium the trend of loop increases which plays crucial role as a Resistive Random-Access Memory (ReRAM) application in switching memory storage devices.

Thermoelectricity is the best technology for converting wasted heat into clean electrical energy. Calcium Bismuth cobaltites Ca2.7Bi0.3-xNdxCo4O9+⸹ was synthesized using WOWs Sol-gel method with (x=0.0,0.05) doped with Neodymium. A structural study was carried out using the X-rays diffraction (XRD), which confirmed the Monoclinic structure of all the prepared samples. The Electrical properties were studied by using two-probe method. The thermal transport properties of the samples were measured at room temperature using the Advantageous transient plane source (ATPS) method. At room temperature thermal conductivity was measured. Seebeck coefficient as a function of temperature measurement revealed that doping Neodymium considerably increases the value of the Seebeck coefficient when compared to previously published values. At the end we measured the figure of merit (ZT).
