Dynamic Electronic Structure in Transition Metal Oxides Jiangong Li1,Haiying He1 (1.Department of Materials Science, Lanzhou University, Lanzhou 730000) 摘要:The isomer shift of La1-xCaxFeO3 decreases gradually from the value for trivalent iron to that for tetravalent iron, as the Ca content x increases from 0 to 1. This indicates that iron in La1.x-CaxFeO3 has an intermediate valence state......
