This study investigates the systematic doping of Cu on the structural and magnetic properties of Li-Cu ferrites synthesized using the sol-gel technique. X-ray diffraction (XRD) analysis confirms the cubic phase structure, while field emission scanning electron microscopy (FESEM) reveals variations in grain morphology with doping concentration. Occupational shift and magneto crystalline anisotropy transition observed due to Cu-Li substitution through Raman spectroscopy. The magnetic behavior of the doped samples demonstrated the decline of the magnetization Ms from 53.32 to 18.12. Coercivity (Hc) increases significantly due to grain refinement and domain wall pinning effects. The tunability of these properties ensures improved stability and performance in sophisticated technological applications such as stable fields in spintronics, data storage systems, transducers, inductors, magnetic sensors, and various energy conversion applications.

摘要

This study investigates the systematic doping of Cu on the structural and magnetic properties of Li-Cu ferrites synthesized using the sol-gel technique. X-ray diffraction (XRD) analysis confirms the cubic phase structure, while field emission scanning electron microscopy (FESEM) reveals variations in grain morphology with doping concentration. Occupational shift and magneto crystalline anisotropy transition observed due to Cu-Li substitution through Raman spectroscopy. The magnetic behavior of the doped samples demonstrated the decline of the magnetization Ms from 53.32 to 18.12. Coercivity (Hc) increases significantly due to grain refinement and domain wall pinning effects. The tunability of these properties ensures improved stability and performance in sophisticated technological applications such as stable fields in spintronics, data storage systems, transducers, inductors, magnetic sensors, and various energy conversion applications.
