【 摘 要 】

Polycrystalline (LaSr)(MnNi)O3was 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)O3with chemical formulation La0,67Sr0,33Mn1-xNixO3with × = 0,05 and 0,10. We report the crystallite structure of La0,67Sr0,33Mn1-xNixO3with x= 0,00 and 0,10 are single phase with characterization by X-ray diffraction. Refinement has result that crystallite size of La0,67Sr0,33Mn0,95Ni0,05O3is 24,67 and La0,67Sr0,33Mn0,9Ni0,1O3is 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-1were 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-1and the dominant peak at wave number 3750 cm-1caused the hidroxy compound in sampel La0,67Sr0,33Mn0,95Ni0,05O3.
