Nanocrystalline spinel Ni0.6Zn0.4Fe2O4: A novel material for H2S sensing

Structural and magnetic properties of nickel–zinc ferrite nanocrystalline magnetic particles prepared by microwave combustion method

“…The quality of fitting is confirmed using the goodness of fit (v 2 ) value. Figure 2(b) shows Rietveld fitted X-ray diffraction pattern for NiFe 2 Figure 2(c) shows effect of HCl wash (each of volume 50 ml) on the impurity peak. The intensity of Ni phase decreases with an increase in the number of washes (A to F).…”

“…Nickel-Zinc spinel ferrite Zn x Ni 1-x Fe 2 O 4 is used in high frequency devices such as dc-dc power converter in switch mode power supplies, electron beam deflector, electromagnetic interference absorbers, filters [1] and gas sensing material [2,3]. In Ni-Zn system, Ni 2?…”

Microwave synthesis and characterization of Zn-doped nickel ferrite nanoparticles

“…By changing type of the divalent cation, it is possible to obtain significantly different physical and magnetic properties in these ferrites. Among the different spinel ferrites, Ni-Zn ferrites have unique properties and are the most versatile magnetic materials for general use in microwave devices, power transformers in electronics, rod antennas, read/write heads for high speed digital tape [8], and gas sensing material [9,10]. Ni-Zn ferrite is a mixed spinel in which T d sites are occupied by Zn 2+ and Fe 3+ ions and the O h sites are occupied by Ni 2+ and Fe 3+ in the lattice [10].…”

Influence of Temperature on Reducing Gas Sensing Performance of Nanocrystalline Zinc Ferrite

“…Materials with particle size in nanometer range, which have high surface activity due to their small particle size and large specific surface area, have been widely studied in the area of gas sensors for different applications [2,3]. A wide range of sensor materials based on metal oxide semiconductors has been developed [4][5][6]. The fabrication of these sensors often uses pellet, thin film, and thick film technology [7][8][9].…”
