| 中文摘要 | The local structural distortion and its effect on the magnetic and magnetotransport properties of the Fe-doped La1-xBaxMnO3 (0.00 <= 0.35) compounds were investigated by means of X-ray diffraction, Mossbauer spectroscopy, and magnetization measurements. The Mossbauer spectra show clear evidence of the local structural distortion of the Mn(Fe)O-6 octahedron on the basis of non-zero nuclear quadrupole interactions for high-spin Fe3+ ions. It was found that the local structural distortion decreases significantly with the introduction of a few per cent of Ba, reaches a minimum around x = 0.13, and then increases slightly on further increasing the Ba concentration. The Ba-concentration dependence of the Jahn-Teller coupling strength estimated from the Mossbauer results was found to be consistent with the magnetic properties. Consequently, the connection between this local structural distortion and the colossal magnetoresistive behavior of this family of materials can be well explained. |
