中文摘要	The local structure of the Fe-doped La1-xCaxMnO3 (x=0.00-1.00) compounds has been investigated by means of Mossbauer spectroscopy. Fe-57 Mossbauer spectra provide direct evidence of Jahn-Teller distortion in these manganites. On the basis of the Mossbauer results, the Jahn-Teller coupling was estimated. It is noteworthy that the Ca-concentration dependence of the Jahn-Teller coupling strength is very consistent with the magnetic phase diagram. Our results reveal that Mossbauer spectroscopy cannot only detect the local structural distortion, but also provide a technique to investigate the Jahn-Teller coupling of Fe-doped La1-xCaxMnO3 colossal magnetoresistive perovskites.
