The praseodymium de5ciency e4ects on the structural, magnetic, and electrical properties of the lacunar perovskite manganite oxides Pr 0.7؊x ) x Sr 0.3 MnO 3 (04x40.23) have been investigated. This study is of great interest because it gives more information on the role of the Mn cation oxidation de
