Giant Anomalous Hall Effect in the Chiral Antiferromagnet Mn 3 Ge
Open accessAbstract
The lineup of moments in an antiferromagnet yields no net magnetization, which means for such a material we expect no useful anomalous Hall effect (AHE) for applications. However, this study identifies an antiferromagnetic compound that, due to its exotic electronic structure, $d\phantom{\rule{0}{0ex}}o\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}s$ show a strikingly large AHE, at room temperature. This is significant for creating nonvolatile memory with minimal stray fields, which allows a much higher bit density than is currently possible, and is also of general interest in the study of correlated electron systems.

Mn3Sn and Mn3Ge exhibit their anomalous Hall effect up to temperatures near the Neel transition near 400 K.
“Also note that these materials exhibit their anomalous Hall effect up to temperatures near Neel transition near 400 K (Kiyohara et al. , 2016; Nakatsuji et al. , 2015).”

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.
