Abstract
The magnetic properties after sintering of Ni0.34Zn0.60Fe2.06O4 from h ydrothermal submicrometer-sized powders were evaluated. The results fr om hysteresis magnetic loops showed high saturation magnetization (500 0 < 4 pi M-s < 7000 G), low remanence (160 < 4 pi M-r < 300 G) and coe rcitivity (22 < H-c < 35 Oe) values. The microstructural evolution was correlated to the magnetic parameters and the relations between them were discussed. The absolute values of saturation were compared to oth er NiZn ferrites of similar composition and obtained from different me thods described in the literature.
