This research carried out experiments on the Chevrel-phase Mo6S6I2 polycrystalline superconductor. The behavior of harmonic generation in the dc magnetic fields, the dependence of the high harmonics on the ac magnetic field amplitude, the dc magnetic field, and the temperature are investigated. The experimental results are well described by the classical Bean critical state model, when the current does not depend on the dc field and even harmonics are not observed.
Key words: Chevrel phase, high harmonics, Bean critical state model.
