Single crystals of double manganites RBaMn2O6 (R = Pr0.5Nd0.5, Nd0.5Sm0.5, Sm) were grown and the magnetic and optical properties in the near-IR range were studied. From the analysis of structural data, partial ordering of the R and Ba ions (A-site ordering) ~50% was confirmed. According to magnetic data, the ferromagnetic contribution decreases and the coercive force increases as the average radius of the rare-earth ion decreases in the series Pr0.5Nd0.5->Nd0.5Sm0.5->Sm. From measurements of the temperature dependences of light transmission a change in the conductivity character from "semiconductor" to "metallic" at cooling was discovered: for manganite with Pr0.5Nd0.5 the conductivity change temperature TMI is close to the magnetic phase transition temperature Tc, and for manganites with Nd0.5Sm0.5 or Sm the TMI value is higher than Tc. Near TMI in the manganites under consideration, the influence of the magnetic field on the transmission of light and the magnetotransmission effect were found. The highest magnetotransmission of 5% is observed in manganite with R = Pr0.5Nd0.5. Keywords: double manganites, ordering, phase transitions, magnetotransmission effect.
