The nanomagnetic structure of hydrothermal NiZn femtes sintered at various temperatures was studied in this work through Magnetic Force Microscopy using different magnetically characterized tips. The magnetic patterns varied according to the tip employed and were correlated to the magnetic induced field generated by these different coated tips. Nickel fenites were produced at 200°C by hydrothermal synthesis and sintered at temperatures ranging from 1100°C to 1400°C.
