Abstract
Colloids of cobalt-substituted magnetite are investigated using ferromagnetic resonance. It is found that the ferromagnetic resonance spectrum consists of two spectral lines. The intensity ratio of these lines depends on the size of the magnetic particles. The experimental results are interpreted in the framework of the Raikher-Stepanov theory. It is established that the average radius of particles increases with increasing time.
