Nanomagnetism and domain structure of sintered nickel-zinc ferrites studied by magnetic force microscopy

The nanomagnetic structure of hydrothermal NiZn ferrites sintered at various temperatures was studied in this work through magnetic force microscopy using different magnetically characterized tips. The magnetic patterns according to the tip employed were correlated to the magnetic induced field generated by these different coated tips. Nickel ferrites were produced at 200/spl deg/C by hydrothermal synthesis and sintered at temperatures ranging from 1100/spl deg/C to 1400/spl deg/C.
