Abstract
Temperature dependent photoresponse of thin La 0.75 Ca 0.25 MnO 3 films to visible and near-infrared laser radiation has been studied in a wide temperature range. At temperatures below 50 K, we have found a non-bolometric contribution to the response which can be explained by suppression of the spin-glass-like ordering in the film due to the absorption of radiation with quantum energy high enough for excitation of spin-flip process.
