Abstract
For a series of epitaxial and polycrystalline manganite/ferrite heterostructures grown on different substrates, the interelation between light transmission in the IR range and electrical resistance, magnetotransmission, and magnetoresistance has been studied in a temperature range of 80–385 K. It has been established that the temperature dependences of transmission and magnetotransmission in the manganite/ferrite heterostructures on different substrates are similar to the temperature dependences in the films of manganites on the same substrates. It has been shown that in a magnetic field of 8 kOe applied perpendicular to the surface of the epitaxial manganite/ferrite heterostructure the magnetotransmission increases by ∼40% relative to its value in the single-layer epitaxial films.
