Abstract

The dc magnetic field and frequency dependences of the transmission coefficient of the four-pole network containing a core made of La0.6Pb0.4MnO3 manganite were studied. It is shown that the frequency dispersion of the magnetic permeability of the core material is large at frequencies of about 100 kHz. The factors which influence the value of the transmission coefficient are analysed. Large low-frequency variations of parameters of the four-pole network containing the magnetic circuit made of manganite can be promising for possible device applications.
