Photoresponse of thin La sub(0.75)Ca sub(0.25)MnO sub(3) films to laser radiation

Temperature dependent photoresponse of thin La sub(0.75)Ca sub(0.25)MnO sub(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 suppressio...

Description
Summary:Temperature dependent photoresponse of thin La sub(0.75)Ca sub(0.25)MnO sub(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.
