Description
Moessbauer effect technique has been used for the study of magnetic properties of spinel series Ni1x Cux Mny Fe2-y O4 with 0.0≤ x -< 1.0, and y=0.6. The substitution of Mn3+ and Cu 2+ ions results in a slight decrease of hyperfine at B- as well as A- sites. Area ratio of Fe3+ ions at A-and B-Site at 77 K indicates that Cu2+, Ni2+ and Mn3+ ions occupy the octahedral sites in an evidence for complete inverse spinel in this system. The temperature dependence of the hyperfine parameters has been studied for composition with X=0.5 where Neel point TN and debye temperature θD are found to be 650 K and 679 K respectively. The sublattice magnetization δ(T) obeys a one-third power law in the range 0.5 <T/TN<0.99
