Abstract
Photostimulated exoemission (PSE) from epitaxial films of the La0.84Sr0.16M nO3 and La0.35Pr0.35Sr0.3MnO3 manganites with colossal magnetoresistance wa s investigated. It was established that the maximum of the temperature depe ndence of PSE lies near the temperature of the ferromagnetic metal --> para magnetic semiconductor phase transition. It was found that the effect of a magnetic field on PSE shows a lag due to a residual ferromagnetism of the f ilm.
