Abstract
The mechanism of growth of nickel ferrite single crystals using the PbOPbF2 as the flux system, has been studied. The nucleation seems to start around 1170°C and the growth rate seems to be quite fast up to a temperature of 1100°C, as indicated by the yield and the size of the crystals obtained at this temperature. The growth rate then slows down appreciably.
The line width of 15 Oe along the 100 axis for the crystals thus obtained, indicate their good quality and a low content of Fe2+. By a thermal treatment, an ionic order is established among the sites and the resulting line width is 9 Oe. This value of 9 Oe for nickel ferrite is the lowest so far cited in the literature.
