In this study the effect of doping vacancy in the place of lanthanum and conditions on the construction of various structural characteristics, magnetic and electricalof La 1-x MnO 3 Manganite discussed. Samples were made by heat acetate resolution method. To investigate the effect of building hunk temperature in the different characteristics of compounds, samples were divided into two series at temperatures 1200 and 1350 degrees centigrade and Hunk were paired samples were low temperature and high temperature were called.. X-ray diffraction pattern analysis of samples showed that the majority compounds have rhombohedra structural than samples x = 0.15 the low temperature thatis orthorhombic structure. Also For samples x = 0.15of high temperature has appeared Mn 3 O 4 impurities phase. In theall samples with an increase vacancy in the place of lanthanum has increased lattice parameters and unit cell volume. Analysis of SEM images taken from samples showed that grain size with increasing building hunk temperature is increases. Howeverthe vacancy range created in samples here, the grain size appears to be with increasing vacancy here are smaller and more homogeneous. Ac magnetic susceptibility diagrams samples showed that in both series with increasing vacancy in the place of lanthanum in the first place Curie temperature increases and then decreases. In samples x = 0.01 and x = 0low temperature, the system state after the transition to a phase Ferromagnetic indicate a cluster spin glass state that because the double exchange interaction in the effect increasing dominance of ferromagnetic phase that this is together with short-range order on the supper exchange interaction mode cloud field with antiferromagnetic phases in the sample. The samples x = 0.05 and x = 0 high temperature, systems after the transition to aFerromagnetic state show the spin glass phase. Ac magnetic susceptibility samples in the temperature range thatis system the spin glass state or a cluster spin glass, dependent to the applied frequency. With investigationdiagrams of electrical resistance of the samples was determined that with increasing vacancy in the place of lanthanum, specific resistivity samples initially decreased and then increased. With matching electrical resistance Diagrams of high temperature samples and low temperature samples by small polaron hopping model indicated that with increasevacancy in the place of lanthanum decreased initially energy of activation Polaron and then increased. This trend is contrary Curie temperature are examples. Keyword : Manganite,Vacancy,La 1-x MnO 3 , Ac Magnetic Susceptibility, Spin Glass,Cluster Spin Glass.
