Abstract
In recent years, spin-based electric devices, i.e., spintronics, have attracted interest in next generation electrical devices—charge flows faster and energy loss is lower. In the case of ferromagnetic material, charge may flow faster but energy loss is high due to its heating effect. The aim is to explore paramagnetic material in spintronics on the basis of spin Hall effect (SHE). This study presents the preparation and characterization of Ni-doped CeO2 by a combustion technique. The characterization was studied by powder X-ray diffraction analysis (XRDA), high-resolution transmission electron microscopy (HR-TEM), vibrating sample magnetometry (VSM), electrical impedance studies, and X-ray photoelectron spectroscopy (XPS) analysis. VSM studies reveal Ni-doped CeO2 is paramagnetic in nature, which will open the possibility of realizing spintronics devices.
