摘要

La_(0.8)Sr_(0.2)MnO_3 (LSMO)/Zn composites were prepared by bonded method. The phase structure, electrical transport and low-field magnetoresistance (LFMR) characteristics have been investigated. The binder segregated mostly at the grain boundaries. The bonded composites exhibited enhanced LFMR, which was attributed to the enhanced intergrain spin-polarized tunneling behavior.
