Abstract

The use of perovskite type compounds, has gained a tremendous applications in various fields like memory storage devices, bolometers, superconductors, solar cells, etc. One of the very important uses of perovskite material is in the construction of bolometers. Bolometers are extensively used in fusion devices for temperature measurement and also in space application. In this paper we have presented the experimental behaviour of the electrical resistivity of the perovskite oxide Eu 1-x Sr x MnO 3 after plasma exposure for different composition. It is found that the compound Eu 1-x Sr x MnO 3 behaves as an insulator for all the values of x, since the effective single electron bandwidth is very narrow. The observed decrease in the resistivity below T MI may be due to the lack of delocalized carriers that contributes for the metallic nature of the sample.
