| 中文摘要 | The magnetic and electric transport Properties of La1-xBaxCoO3 (0 < x <= 0.50) have been studied systematically. Two effects of substitution divalent ions on the spin-state transition of Co3+ have been differentiated for the substitution of Ba2+ for La3+ in La1-xBaxCoO3. The first is the transition from low-spin state to high-spin state due to lattice expansion, and the second is the transition from low-spin state to intermediate-spin state caused by the strong hybridization between ligand (oxygen) 2p and Co 3d orbital with introduction of holes in the oxygen 2p orbital. Based on the two different spin-state transition mechanisms and experimental results, a phase separation model has been developed and a very detailed magnetic and electric phase diagram of La1-xBaxCoO3 has been constructed.
