IR Magnetotransmission in Double Manganite NdBaMn2O6 with Different Degrees of Order in A-Position

The study investigated the dependences of the structural, magnetic, and optical properties of double manganites NdBaMn2O6 on the degree of order of Nd and Ba atoms in the A-position. Analysis of the temperature dependences of light transmission showed the changes of the charge carrier subsystem in the region of structural and magnetic phase transitions. If there was a metal–insulator transition, the magnetotransmission near the Curie temperature was detected.
