In recent years, lot of efforts have been made to develop many types of infrared detectors for applications in the field of industry, medicine, science, military and remote sensing. Different applications have different requirements for sensitivity,speed,power etc. LaBaMnO3(LBMO)is a Perovskite metal-oxide manganite material which shows large CMR effect and has been suggested for uncooled bolometer. However,the research work done on the basic properties of this material in connection with the bolometer applications is very limited. In this material, the maximum of the TCR occurs in close...
