摘要: We report measurements of resistance and thermopower of RE1.2Sr1.8Mn2O7+δ (RE=Nd, Pr) ceramics up to a magnetic field of 5 T. Nitrogen annealing has dramatic effects on the transport in reducing the resistivity, shifting peak resistivity to a higher temperature, and shifting thermopower to more negative values. The value of ΔJT increases as a result of nitrogen annealing, indicating an enhanced Jahn–Teller distortion due to the increased Mn3+ concentration. These results are consistent with the effects of nitrogen annealing on the transport of RE=La.
