Superparamagnetic behaviour: CoO nanosheets synthesised by a surfactant‐free wet chemical route (see high‐resolution morphology image in figure), exhibit superparamagnetic features different from their bulk counterparts. No distinct antiferromagnetic transition around 300 K is observed in the nanosheets (see spectra).
