The magnetic domain structure, its transformation with temperature, and the magnetization reversal in 20 nm La_{0.7}Sr_{0.3}MnO_{3} film grown on LaAlO_{3} substrate by off-axis magnetron sputtering at 700°C and post-annealed at 600°C were studied in a wide temperature range. The magnetic domains with either in-plane- or out-of-plane-orientation of the vector of spontaneous magnetization were observed in the same film depending on the prehistory. The domains with the in-plane magnetization were found to be more stable. Magnetization reversal of the film was shown to occur via the nucleation and motion of 180-degree head-to-head domain walls, the number and the type of which were found to be dependent on temperature. Moreover, the transition between two magnetization reversal regimes was found at 30 K.
