[ 1 ] - خواص الکتریکی و مغناطو مقاومت بین دانه ای در نانو منگنایت La0.7(Sr 1-xBax)0.3MnO3

In this research single phaseLa0.7(Sr 1-xBax)0.3MnO3(x =0, 0.1 , 0.2 , 0.3) nanomanganite with crystalline size of 18-28 nm have been prepared by sol gel method. The structural properties have been studied using X-ray diffraction spectra with its Rietveld analysis and scaning electron microscope images. The magnetic and elctrical properties have been investigated by measuring the ac magnetic su...
