Polycrystalline (LaSr)(MnNi)O3 was shintesized using sol gel methods with nitrat precursors La(NO3)3, Sr(NO3)2, Mn(NO3)2.4H2O, and Ni(NO3)2.6H2O and the different heating process. Sample (LaSr)(MnNi)O3 with chemical formulation La0,67Sr0,33Mn1-xNixO3 with × = 0,05 and 0,10. We report the crystallite structure of La0,67Sr0,33Mn1-xNixO3 with x= 0,00 and 0,10 are single phase with characterization by X-ray diffraction. Refinement has result that crystallite size of La0,67Sr0,33Mn0,95Ni0,05O3 is 24,67 and La0,67Sr0,33Mn0,9Ni0,1O3 is 21,84 with crystallite system rombohedral, it show us that increasing at Ni composition influence of decreased crystallite size. Sampel (LaSr)(MnNi)O3 has been characterization with Fourier Transform Infrared with range of wave number from 450 to 4000 cm-1 were chategories at mid infrared wave. The FTIR pattern show to us that the Mn-O-Mn bounded has absorp infrared at wave number 605 cm-1 and the dominant peak at wave number 3750 cm-1 caused the hidroxy compound in sampel La0,67Sr0,33Mn0,95Ni0,05O3.
