Moessbauer study of the system Ni0.65Zn0.35Fe2-xScxO4

Moessbauer study of the system Ni0.65Zn0.35Fe2-xScxO4, with x values ranging from 0.00 to 0.25, has been conducted at room temperature to analyze the site occupancy of Sc3+ ions. The results indicated that all of the scandium ions preferentially occupy octahedral sites for x values up to 0.10, whereas for the subsequent increase in x, a small part of the scandium ions occupy tetrahedral sites as well. Ionic distribution for the system is given. The observed variations in the hyperfine magnetic fields and peak-area ratios, isomer shifts and linewidths with composition are discussed
