Doping of Nano Cobalt Ferrites by Cupper: Structural and Magnetic Properties Studies
A series of Cupper-substituted cobalt nano ferrites (CuxCo1-x Fe2O4 with = 0.00, 0.10, 0.20, 0.30 and 0.4) was synthesized via hydrothermal method. The structural characterizations of all the prepared nanoparticles were performed using powder x-ray diffraction, EDAX and FTIR analyses. These studies confirmed the formation of single-phase spinel structure in at lower compositions. The increase in the value of lattice ... إقراء المزيد

Electrical, thermoelectrical and magnetic properties of approximately 20-nm Ni-Co-O nanoparticles and investigation of their conduction phenomena
Understanding the properties of semiconductor nanostructures is important for developing their practical applications in the nanodevices. Although the electrical properties of spinel oxides containing Ni and Co have been studied extensively over the last decades, there is still a significant disagreement on their electrical conduction mechanisms and the distribution of the various charge states of Co and Ni in the ... إقراء المزيد
