This dissertation is relation to SrO(La2/3Sr1/3MnO3)n the manganese oxides with RP structure. We mostly studied the structure and electrical transport properties, The major studies are listed below: The classes of magnetoresistance were introduced, the electron and crystal structure and the mechanism of double exchange of manganite pervosike related to colossal magnetoresistance have been summarized. More attention had also been paid to the advance in the study of RP structure manganite and grain system. The principle and process of sol-gel method were introduced. With sol-gel method a series of different grain size La2/3Sr1/3MnO3 sample were prepared.
