abstract = "Ni-Co ferrites, especially the ones with lower cobalt fractions,
are candidate materials for applications in magnetomechanical
sensors and electromagnetic wave absorbers. This work studied the
microstructure, magnetostriction, flexural strength, and complex
magnetic permeability of Ni0.9Co0.1Fe2O4, presenting data that
weren't covered by previous literature on this composition. It was
found that sieving the calcined powder before the forming
operation increased the flexural strength of the ceramic. The
Ni-Co ferrite had a saturation magnetostriction of 36ppm. The real
part of the complex magnetic permeability varied between 2.2-2.3
in frequencies from 100MHz to 1GHz. In frequencies higher than
1GHz, mu' decreased sharply and reached 1 at 3.9GHz. It was found
that the grinding media provided a small fraction of Al to the
ferrite composition, which apparently affected the complex
magnetic permeability of the material but the magnetostriction
results were very close to Al-free Ni-Co ferrites with similar
composition.",
