| contents | Advancements in 2D magnetic materials highlight their potential in semiconductors, magnetism, and spintronics, particularly in tuning magnetic properties for spintronic applications. This study investigates the impact of low-energy (30 KeV) Au ion implantation on 2D layered exfoliated $Cr_2Ge_2Te_6$ flakes prepared on Si/SiO$_2$ substrates using the Scotch tape method. Five different ion doses (5$\times10^{13}$, 1$\times10^{14}$, 5$\times10^{14}$, 1$\times10^{15}$, and 2.5$\times10^{15}$ ions/cm$^2$) were used to modify the morphology, composition, structural, and vibrational properties of the samples. The implantation introduces significant changes in morphology and magnetic behavior, leading to an increase in Curie temperature and an attribution from superexchange to double exchange interactions. The reduced exchange energy gaps and modified magnetic moments attribute to Au ions intercalation in $Cr_2Ge_2Te_6$ underscore the potential of ions implantation to tune the magnetic properties of 2D materials for advanced spintronic applications. |
