According to the abstract released by the Intellectual Property India: "The present invention relates to a system and formulation for synthesis of Gd3+ doped nanocrystalline cobalt-zinc ferrites (CZG). The invention provides a comprehensive system for synthesizing and evaluating Gd3+ doped nanocrystalline cobalt-zinc ferrites (CZG). This system integrates essential components and tools to fabricate, assess, and analyze the ferrites. It encompasses a glass container for mixing chemicals with deionized water, a pH detection device, magnetic stirrer linked to a hot plate, grinding apparatus, and an annealing system to obtain the desired ferrites. Characterization tools such as diffractometer, SEM, TEM, and VSM aid in evaluating the ferrites' structural, morphological, and magnetic properties. The results reveal the formation of pure cubic spinel phases, decreasing particle size with Gd3+ doping, nanocrystalline nature of the particles, and variations in magnetic behaviors. These findings suggest potential applications in magnetic devices, signifying significant advancements in tailored magnetic materials. The electrical resistivity behavior is studied by using impedance analyzer which shows the decrease in resistivity with the increasing frequency and Gd composition (x). The gas sensing of the materials in the form of pellets is studied for LPG, SO2, NO2 and H2 and H2S gases. The materials exhibit highest response for the H2S gas. Amongst the all Gd compositions (x), the material with x = 0.025 exhibits the best sensing parameters such as lowest response times, high sensitivity and log time durability."
