摘要：

The structural, transport, and magnetic properties of bulk SmBaxSr1-xCo2O5+delta samples were investigated as a function of Ba content. At room temperature the magnetization was observed to increase as a function of decreasing Ba composition. As the samples were cooled below room temperature, a ferromagnetic transition was observed for 0.1 <= x <= 0.5 with the Curie temperatures showing a linear dependence on the Ba-composition. Transport measurements showed that resistivity values increased with decreasing temperature indicating a semiconducting-like behavior. (c) 2018 Author(s).
