WebThe anomalous Nernst effect in Mn3Sn(a) In the anomalous Nernst effect, the electromotive force is generated perpendicular to both the magnetization and thermal gradient. (b) As a result, the large anomalous Nernst signal can be observed with spontaneous magnetization as shown in (b). WebInstead, the Nernst peak at the crossover indicates a change in carrier entropy when entering the strange-metal state. The presence of such an anomalous Nernst response …
In physics and chemistry, the Nernst effect (also termed first Nernst–Ettingshausen effect, after Walther Nernst and Albert von Ettingshausen) is a thermoelectric (or thermomagnetic) phenomenon observed when a sample allowing electrical conduction is subjected to a magnetic field and a temperature gradient normal (perpendicular) to each other.
