About this list

Diamond open access (also called Platinum) means the journal is free to read and free to publish in. The journals above are those the DOAJ records with "APC: no" and "other fees: no" and that SCImago lists under the subject area Physics and Astronomy (a journal can belong to several areas). Quartiles come from SCImago's SJR ranking for the latest edition: Q1 is the top 25% of journals in a category, Q4 the bottom 25%. Journals that are in the DOAJ but not in Scopus have no quartile and are not counted here; the finder can show them too.

Before submitting, always confirm the journal on its own website and in the DOAJ, verify Scopus indexing by ISSN with the Scopus check rather than trusting claims on the journal's site, and be wary of look-alike titles.
