Why the theoretical calculation of percentage atom varies from measured data from EDX study?

I am wondering why there is a variation in the theoretical atomic percentage in Ni-Cu ferrites and the percentage atom values found from EDX spectra. In the case of Fe and O, there exists this...

FTIR strong bands near 665 cm-1 and 2350 cm-1 in the study of Cu substituted Ni-Cd ferrites, what is the best explanation?

We used sol-gel method to synthesize Cu substitued Ni-Cd ferrite nanoparticles. XRD patterns confirmed the single-phase spinel structure of the materials. In the FTIR spectra we got absorption...
