The original version of this article was published with the following error. This has been corrected with this erratum.

The sentence “The VSM study revealed that the undoped ZnO and Er doped ZnO nanostructures exhibit paramagnetic and ferromagnetic behaviour at room temperature respectively” should be read as “The VSM study revealed that the undoped ZnO and Er doped ZnO nanostructures exhibit diamagnetic and ferromagnetic behaviour at room temperature respectively” in abstract section and in other occurrences.
