Electrical Conduction Mechanisms of Particulate Magnetoelectric Composite (x)Mn0.4Zn0.6Fe2O4–(1 – x)PbZr0.53Ti0.47O3

Аннотация

The electrical conduction of particulate magnetoelectric composite (x)Mn_0.4Zn_0.6Fe₂O₄–(1 ‒ x)PbZr_0.53Ti_0.47O₃ with х = 0.6, 0.8, and 1.0 is studied at frequencies of 2 to 50 kHz in the 290–670 K range of temperatures. The mechanism of electrical conduction in the composite is shown to change as the temperature rises: the hopping of small-radius polarons becomes the zone transfer of charge carriers.
