Magnetic enhancement in nano-sized Ni Zn ferrite - NASA/ADS

This magnetic enhancement has mostly been prompted by cation redistribution in the nanosized sample. Zinc having strong A site affinity determines the nature and intensity of site exchange of cations, which has a strong influence in the genesis of enhancement/reduction in magnetic property of nano-crystalline Ni Zn ferrite samples.
