Under the assumption the metadata is bibtex native, some publishers put the article number (biblatex =eid, electronic identifier) into the pages field. This can happen, because the bibtex standard (unlike the biblatex standard) is very old, unmaintained and does not have a field for eid, so publishers somehow have to work around the issue. The pages field was chosen, because if an article has an eid, then usually it is published on a webpage and electronic articles do not always have page numbers. If you scroll down at https://advanced.onlinelibrary.wiley.com/doi/10.1002/adma.202416763 you will see that there are no page numbers visible. Also, the when you export the citation directly from the journal, you will end up with the following bibtex metadata:

abstract = {Abstract Spin-orbit torque (SOT) offers an efficient mechanism for manipulating the magnetization of ferromagnetic materials in spintronics-based memory and logic devices. However, conventional SOT materials, such as heavy metals and topological insulators, are limited by high crystal symmetry to generating and injecting only in-plane spins into the ferromagnet. Low-symmetry materials and symmetry-breaking strategies have been employed to generate unconventional spin currents with out-of-plane spin polarization, enabling field-free deterministic switching of perpendicular magnetization. Despite this progress, the SOT efficiency of these materials has typically remained low. Here, a large SOT efficiency of 0.3 in the bulk Ni4W at room temperature is reported, as evaluated by second harmonic Hall measurements. In addition, due to the low crystal symmetry of Ni4W, unconventional SOT from the out-of-plane and Dresselhaus-like spin components are observed. Notably, a large SOT efficiency of 0.73 is observed in W/Ni4W (5 nm), potentially resulting from additional interfacial contributions or extrinsic effects. Furthermore, field-free switching of perpendicular magnetization has been achieved using the multi-directional SOT of Ni4W, highlighting its potential as a low-symmetry SOT material for energy-efficient spintronic devices.},

As you can see, they put a large number into the pages field. Such a large number usually is not really a page number, but rather an eid.
When I download from DOI via JabRef, I end up with the following data:

Itâs different, because we do not query from the journal directly, but from other datasources. Mostly from Crossref.
