| چکیده | ||
| This study presents the synthesis and characterization of the double perovskite compound PrBaMn2O6 was synthesized using a combustion method. Thermogravimetric analysis (TGA) was employed to determine the optimal synthesis temperatures, while sintering was carried out under air to achieve phase purity. The structural and magnetic properties of the material were investigated using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron imaging microscopy (FESEM), vibrating Sample Magnetometry (VSM) and Alternating Current Magnetic Susceptibility (AC susceptibility) analyses. Rietveld refinement using foolproof confirmed a dominant tetragonal structure with space group P4/mmm, accompanied by a minor hexagonal BaMnO₃-type phase. This dual-phase composition introduces lattice strain and partial disorder, which significantly influence the magnetic response. Magnetic measurements at room temperature indicated paramagnetic behavior, suggesting the absence of long-range magnetic ordering. The observed magnetization is attributed to the paramagnetic response of the material, as confirmed by both VSM and AC susceptibility measurements, with the latter revealing a suppressed transition below 200 K due to competing interactions from the secondary phase. | ||
