摘要：

The resistance relaxation after switch-off of high magnetic field pulses of 20-40 T was studied for two series of La0.67Ca0.33MnO3 thin films. The response dynamics was obtained for temperature range 77-300 K. It is shown that the relaxation time is sensitive to the temperature of the resistivity maximum and to magnetoresistive properties of a film. The observed relaxation times are assumed to be related to existence of magnetic domains or intergrain material.
