Why does Curie temperature stabilize after initial drop with Cr³⁺ substitution in Ni-Cu-Zn spinel ferrites?

I have synthesized Ni-Cu-Zn spinel ferrites via the solid-state method and partially substituted Fe³⁺ with Cr³⁺ at the B-site. The parent sample shows a Curie temperature (Tc) of 795 K. With 2%...
