We report the novel result regarding the observation of unusual magnetic behavior with high magnetic moment (higher than reported so far) at room temperature in highly pure ZnO nanorings synthesized by a simple chemical route using cetyltrimethyl ammonium bromide. The enhanced magnetization is attributed to the huge number of surface spins associated with defects created due to the larger surface to volume ratio of nanorings. The present study demonstrates that ZnO samples can be made highly magnetic just by tailoring the nanostructure even without doping transition-metal. Some new magnetic features have been observed and possible explanations are delineated here.
