摘　　要：We report the preparation of epitaxial La_(0.7)Sr_(0.3)MnO_(3) thin films grown on(001)-oriented 0.72Pb(Mg_(1/3)Nb_(2/3))TO_(3)-0.28PbTiO_(3) substrates by the sol–gel technique.The phase structure,magnetic properties and magnetoresistance of the samples are investigated by using high solution X-ray diffraction,atomic force microscopy,physical property measurement system,respectively.The La_(0.7)Sr_(0.3)MnO_(3) thin films display a well-defined hysteresis loop and typical ferromagnetism behavior at lower temperature.High magnetoresistance at 5 T of 42%appears at 227K for La_(0.7)Sr_(0.3)MnO_(3) thin film.
