Abstract
We report X-ray diffraction, resistivity, thermopower, and magnetization of Sr3ErMn4-xGaxO10.5-dSr3ErMn4-xGaxO10.5-d, in which A-site ordered tetragonal phase appears above x=1x=1, and reveal that the system exhibits typical properties seen in the antiferromagnetic insulator with Mn3+Mn3+. We succeed in preparing both A-site ordered and disordered phases for x=1x=1 in different preparation conditions, and observe a significant decrease of the resistivity in the disordered phase. We discuss possible origins of the decrease focusing on the dimensionality and the disordered effect.
