Magnetic and dielectric properties on sol-gel combustion synthesis of Pb(Zr_(0.52),Ti_(0.43)X_(0.05))O3 (X = Fe, Ni, and Co) nanoparticles

摘要

Pure and X-doped (X = Fe, Ni, and Co) PZT nanoparticles (PZT-NPs) were synthesized by a sol-gel combustion method. The structural characterization of the obtained pure and doped PZT-NPs was carried out by X-ray diffraction (XRD). The crystallite size of the prepared samples was then evaluated by the size strain plot (SSP) method using the XRD results. The average particle sizes of 30-40 nm were measured for pure and doped PZT-NPs by a particle size analyzer. For dielectric measurements, the synthesized powders were pressed into pellets and then sintered at 1250 °C for 2 h. The magnetic properties of the synthesized doped PZT-NPs were studied by a vibration sample magnetometer (VSM) and ferromagnetic behavior was observed.
