Tunneling Magnetoresistance of La_(0.7)Sr_(0.3)MnO_3 Ceramics Obtained by Complexonate Homogenization

摘要

The discovery of colossal magnetoresistance (CMR) in doped manganites R_(1-x)A_xMnO_3 (R=La,Pr,Nd;A=Ca,Sr,Ba,Pb) with a perovskite structure has drawn the attention of researchers to these complex oxides as a new class of magnetosensitive materials [1-4].
