Effective generation of the harmonics of magnetic flux in a toroid made of lanthanum manganite

The nonlinear processes related to the magnetization reversal of the two-port with the magnetic core made of the lanthanum manganite doped with lead in the presence of crossed static and RF magnetic fields are studied. The effective harmonic generation is demonstrated at relatively large amplitudes of the RF excitation field and a relatively strong static magnetic field. The experiments are performed at the excitation field frequencies ranging from 5 to 150 kHz and static fields of up to 10 kOe. Both even and odd harmonics (up to the tenth harmonic) are observed.
