Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In order to investigate the effect of sintering temperature on the structure and properties of Zn–Co ferrite, the ZnCoFeO ferrite powder with spinel structured was prepared by sol–gel method at different sintering temperatures. X-ray diffraction spectroscopy (XRD), Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) were used to study the structural and magnetic properties of the prepared samples. It was found that the sintering temperature has a significant influence on the structure and magnetic properties of the Zn–Co ferrite. As the sintering temperature increases from 600 to 1000 °C, the crystallinity and crystallite size of the samples increase significantly, but the coercivity, remanence, and squareness decrease and the saturation magnetization increases first and then decreases. Compared with other samples, the sample sintered at 900 °C has the highest bulk density (3715.42 kg/m) and saturation magnetization (68.17 emu/g). At the same time, it also has a small coercivity, remanence, anisotropy constant, and porosity. The sample obtained by sintering at 800 °C has a good magnetic susceptibility (dM/dH) at H. This work provides basic research data for the preparation of Zn–Co ferrite with better magnetic properties and has certain reference value.
