Structure–magnetism correlation in (Co0.8Ni0.2)Fe2O4 nanoparticles: Effect of calcination temperature on domain transition and microwave response

Key Points

• Microwave response varies significantly with changes in calcination temperature, affecting magnetism.
• At higher calcination temperatures, an observable shift in domain transition occurs, enhancing magnetic properties.
• Analysis of nanoparticles focuses on their structural and magnetic characteristics linked to calcination temperature.
• These findings suggest important implications for designing effective magnetic materials and devices.
