Data availability statement policy

Mandatory data availability statement policy

IOP Publishing encourages all authors to make the data underpinning their article available to editors, referees and readers without undue restriction wherever possible.

For the following journals, authors must provide a data availability statement in their article that details whether data are available and, if so, where they can be found.

Authors of accepted articles in these journals may deposit their data and/or code free-of-charge in the IOP Publishing Figshare repository by following the link supplied during the article submission process.

For other IOP journals we strongly encourage the inclusion of a data availability statement, but it is not a requirement.

Permissible formats for data availability statements

Data availability statements should follow one of the following formats and should appear in their own section of the manuscript, between the Acknowledgments and the References.
