Abstract: | Intense exoemission near phase transitions of epitaxial films of the La0.16Sr0.84MnO3 and La0.35Pr0.35Sr0.3MnO3, manganites, which exhibit the colossal magnetic resistance (CMR), is detected in a wide temperature range from 278 to 623 K including the Curie temperature. The role of the absorbed and lattice oxygen in the exoemission and CMR phenomena is discussed. The aftereffect of the magnetic field directed along the film plane on the intensity of photostimulated exoemission is discussed. |
