5. Conclusions
As a conclusion, we can state that ferrites are complex materials: they offer a crystal
complexity, with complex magnetic structures and complex magnetic properties. However,
complexity can always be a rich source of knowledge. In addition to the well known
ferromagnetic resonance methods, some significant steps can be done by investigating the
microwave response of ferrites, particularly by using two novel research techniques, based
on nonresonant absorption: low field and magnetically modulated microwave abosorption,
which provide an original insight into these materials.
