Highlights: [•] La0.67Ba0.33x□ x MnO3 manganites crystallize in the rhombohedral structure. [•] Barium vacancies modify the structural parameters such as the volume, the Mn–O bond length and the Mn–O–Mn angles. [•] La0.67Ba0.33x□ x MnO3 exhibit a PM-semiconducting state at high temperatures and a FM-metallic state at low temperatures. [•] The resistivity is described in terms of percolation phase theory in the whole range of temperatures. [•] The Curie temperature TC and the electrical transition temperature T M-SC decrease with increasing barium deficiencies. [ABSTRACT FROM AUTHOR]
