ABSTRACT

The polycrystalline undoped and Mn doped ZnO (Zn0.85Mn0.15O) nanocrystals were successfully synthesized using solid state reaction technique. The X-ray diffraction (XRD) studies of pure ZnO and Mn doped ZnO nanocrystals exhibit the wurtzite structure (hexagonal phase, space group P63mc) with high crystallinity and also without any impurity phases. Surface morphology and particle size were carried out using transmission electron microscopy (TEM). It shows that these nanoparticles are of hexagonal phase ZnO mostly in spherical shape with average diameter of the nanocrystals were in the range 30 -100 nm. The magnetic measurements by vibrating sample magnetometer (VSM) clearly indicate that the pure ZnO nanocrystals are in ferromagnetic nature and Mn doped ZnO nanocrystals exhibit co-existence of paramagnetic and ferromagnetic behavior at room temperature.
