Özet:

 

Under varying temperature conditions, undoped   Y22_{2}Si22_{2}O77_{7} and neodymium-doped Y22_{2}Si22_{2}O77_{7}   nanopowders were synthesized by the sol-gel method. The phase transitions   from αα\alpha  to δδ\delta  were observed in neodymium nanopowders by XRD   measurements. TEM images showed ball-shaped structure forms for synthesized   samples. The elemental compositions of all samples were established and   quite close stoichiometry to all compound formulas was found using an   attached component for TEM. To reveal the Nd dopant effect in   different-phased Y22_{2}Si22_{2}O77_{7} nanopowders, diffuse reflectance   measurements were conducted. To establish the magnetic properties of undoped   Y22_{2}Si22_{2}O77_{7} and neodymium-doped Y22_{2}Si22_{2}O77_{7}   nanopowders, an extensive study was carried out including M-H, M22^{2}-H/M   (Arrott's plot), and M-T under varying physical conditions. In the αα\alpha    phase, a significant paramagnetic increase was observed and a decrease in   paramagnetic behavior was monitored by the effects of Nd dopant and   increased annealing temperature.
