| Abstract: | Gd1?xBixFe1?yZryO3 nanoparticles were synthesized via micro-emulsion route with different molar concentrations of Bi+3 (x) and Zr+4 (y). The values of x and y were kept in the range 0.00, 0.15, 0.30, 0.45 and 0.60. The characterizations were done by the thermo-gravimetric analysis (TGA), X-ray Diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The average particle size was ~50 nm. The effect of Bi3+ and Zr4+ contents on electrical, dielectric and magnetic parameters were studied. The DC resistivity measurements showed at certain Bi3+ and Zr4+ contents, more than two fold increase in electrical resistivity from 68×108 Ω cm to 150×108 Ω cm. The magnetic measurements showed the paramagnetic nature of Gd1?xBixFe1?yZryO3 nanoparticles. The electrical and magnetic properties of these nanoparticles suggested that these materials are potential candidates for the fabrication of telecommunication and switching devices. |
