Abstract: Na co-doped ZnO: Mn, or Zn0.96-xMn0.04NaxO nanoparticles, were synthesised using a wet chemical co-precipitation process with x ranging from 0.00 to 0.04 and are reported here. A superconducting quantum interference device (SQUID) was used to investigate the magnetic properties of the nanoparticles. Weak room-temperature ferromagnetism (RTFM) is observed in magnetisation experiments, and it becomes stronger as the Na concentration increases. There is a substantial link between the observed RTFM and oxygen vacancy defects produced by Na doping. To understand the fundamental mechanism of ferromagnetism in dilute magnetic semiconductor systems, the Na doping is correlated with the observable magnetic characteristics of the current system. Near-zero field data is shown in the insets, highlighting the samples' relative coercivity and remanence magnitudes. Furthermore, the magnetic moment increases with the rise in Na concentration from 2% to 4%, rising from 2.8 to 4.0 emu/g at 5 K.
