Abstract

We report the optical responses of magnetic manganese oxide La2/3Ca1/3MnOδthin films at room temperature. The voltage responses to a He-Ne laser at the wavelength of 0.63 μm and incident infrared (IR) power at the wavelength of 8-14 μm were measured. The measured signals were attributably to a bolometric response due to the heating of the sample by radiation. We report the optical responses in La2/3Ca1/3MnOδthin films as a function of chopping frequency and bias current. The noise behavior around room temperature was also discussed. It is suggested that perovskite manganese oxide thin films are suitable candidates for uncooled optical detectors.
