英文摘要	The structure and magnetoresistance properties in sintered samples of la-2/3 ca-1/3 mn1-x fexo3 (0 less than or equal to x less than or equal to 0.84) are studied by using mossbauer spectroscopy, xrd and magnetic measurement. there are antiferromagnetic interactions between fe and its nearest neighbors (fe, mn) when 0 less than or equal to x less than or equal to 0.67, which are important factors influencing the double-exchange between mn3+ and mn4+, curie temperature, magnetic moment and gmr. it is suggested that the mn3+(fe3+)/mn4+ system also consists of magnetic clusters with different sizes.
