Resumen

The electric and magnetic properties of a phase separated manganite were studied by investigating the effect oxygen vacancies on the compound. At a temperature below 240 K the compound exhibited paramagnetic to ferromagnetic (FM) transition, while around 175 K charge-ordered (CO) and antiferromagnetic phases were observed. The introduction of Oxygen vacancies enhanced FM ordering and thereby decreased the resistivity and magnetoresistance.
