摘要：

The reversible charge ordering transition of (Sm(1-x),Ca(x))MnO(3) is associated with strong changes in electrical, magnetic, and infrared properties. In this work, normal spectral emissivity is calculated from infrared reflectance of bulk polished ceramics. Emissivity versus temperature shows a sharp variation at the charge ordering transition near room temperature. By comparing the apparent temperature of the sample with the absolute temperature, we show that Sm(0.35)Ca(0.65)MnO(3) is a good candidate for infrared furtivity around room temperature.
