摘要：
The structural and magnetic properties of La0.6-xYxSr0.4MnO3 (x = 0-0.3) manganite synthesized by the sol-gel method was systematically investigated. The structural properties of the samples were investigated using X-ray diffraction (XRD) patterns and confirmed by Rietveld refinement analysis. Using the energy dispersive X-ray (EDX) analysis, the atomic percentage of the elements in the samples was confirmed. To investigate the surface morphology of the specimens, a field emission scanning electron microscopy (FESEM) analysis of the specimens was performed. The effect of yttrium substitution on the magnetic properties of the samples was also investigated. The Curie constant, magnetic moment, blocking temperature, and Curie temperature (T-c) were calculated using the Curie-Weiss law and the magnetic susceptibility of the samples.
