Recently there has been great interest in doped manganite thin films exhibiting colossal magnetoresistance (CMR), in particular for magnetic sensing applications. These perovskite oxides exhibit a metal-insulator transition at the Curie temperature which is accompanied by a large change of resistance as the material loses its ferromagnetic properties. Since this resistance change occurs over a relatively narrow temperature range it is accompanied by very large temperature coefficients of resistance in the region of the phase transition, making these materials ideal candidates for infrared detectors utilizing resistance bolometers. This paper reports measured physical and electrical properties, the latter including 1/f noise, of doped manganite thin film CMR material deposited by pulsed- laser deposition. The potential performance of CMR based resistance bolometer devices is reported.
