Popis: | A flexible chemical solution deposition (CSD) method for the preparation of magnetoresistive La1−x (Ca,Sr)x MnO3thin films based completely on metal propionates is pre-sented.A number of polycrystalline thin films with varying stoichiometries were deposited on different substrate ma-terials at temperatures between 550° and 850°C. The crys-tallization behavior on selected substrates was found to de-pend on the thin film stoichiometry. Magnetoresistivity and magnetization were measured as a function of temperature. For the selected samples, a magnetic Curie temperature TC, a metal–semiconductor transition, and magnetoresistive behavior were observed. These measurements demon-strated that La1−x(Ca,Sr)x MnO3 thin films with properties well known from films deposited by PLD or sputtering can be prepared by a simple, propionate-based CSD method. |
