All-in-all-out magnetic domain wall conduction in a pyrochlore iridate heterointerface
Open accessAbstract
Metallic surface states emerging at all-in-all-out type antiferromagnetic domain walls in bulk pyrochlore iridates have recently been observed. Such bulk crystals, however, inevitably contain huge amounts of the domains at random, and so it is quite challenging to investigate and utilize these novel surface conducting states. The results presented here are for a pyrochlore iridate heterointerface, which is realized by an advanced thin film growth technique. The authors successfully demonstrate the detection and control of a surface state linked to the antiferromagnetic domain wall, guiding further efforts for utilizing such states for surface transport in electronics and spintronics applications as well as for investigating the emergent topological transport at the interface.

Metallic domain wall conduction was reported in A=Nd pyrochlore iridates.
“Indeed such metallic domain wall conduction was reported in A=Nd pyrochlore iridates (Fujita et al. , 2016; Ma et al. , 2015; Ueda et al. , 2014) indicating proximity to a Weyl semimetal.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
