Effect of Co content on magnetic features and SPIN states IN Ni–Zn spinel ferrites - ScienceDirect
Source: sciencedirect.com
Article summary:
1. This article examines the effect of Co content on the magnetic properties of Zn0·3Ni0·7Fe2O4 spinels, in which Ni2+ ions are partially substituted by Co2+ ions.
2. The linear increase in the lattice parameters with increasing cobalt content was explained by the difference in ionic radii Co2+/Ni2+.
3. Curie temperature decreased from 419°C to 326°C with increasing Co content from x=0.0 to 0.7, respectively, while an increase in Ms; Mr and Hc was observed due to the larger magnetic moment of the Co2+ ion in comparison with Ni2+.
Article analysis:
This article provides a detailed analysis of the effect of Co content on the magnetic properties of Zn0·3Ni0·7Fe2O4 spinels, in which Ni2+ ions are partially substituted by Co2+ ions. The authors use solid-state reaction as a synthesis method and XRD analysis to determine structural parameters and Curie temperature. The results show that an increase in Co content leads to a decrease in Curie temperature and an increase in Ms; Mr and Hc due to the larger magnetic moment of the Co2+ ion compared to Ni2+.
The article is generally reliable and trustworthy, as it provides detailed information about its research methods and results. However, there are some potential biases that should be noted.
