Resumen:
We have made a systematic study of the magnetic properties of low doped manganite films submitted to different oxygenation treatments.We have found that oxygenation dynamics depends critically of the strain field in the sample. The T and the Mr increase as the oxygen content is increased. A decrease of the coercive field of the LSMO-STO films was observed,indicating that annealing treatments increase the oxygen content reducing oxygen vacancies.
