Examines magnetic softness and tailoring strategies in CoZnFe nanoferrites, suggesting new applications.
mode confirms progressive tetrahedral distortion and cation rearrangement. The nanoferrites exhibit soft magnetic behavior with high saturation magnetization (51-58 emu/g) and low coercivity (20-79 Oe). The law of approach to saturation (LAS) analysis reveals a marked decrease in the anisotropy constant, primarily attributed to the dilution of octahedral Co²⁺ ions, reinforced by Al³⁺-induced A-B exchange weakening and nanoscale spin canting. These findings demonstrate that controlled multi-cation substitution provides an effective strategy for tailoring magnetic softness and anisotropy, making the materials promising for spintronics, high-frequency electronics, magnetic sensing, and electromagnetic interference shielding applications.
