Origin of negative anomalous Nernst thermopower in Mn-Ga ordered alloys
Origin of negative anomalous Nernst thermopower in Mn-Ga ordered alloys
The negative sign of the anomalous Nernst thermopower ($S_\text{ANE}$) observed in Mn-Ga ordered alloys is an attractive property for thermoelectric applications exploiting the anomalous Nernst effect (ANE); however, its origin has not been clarified. In this study, to gain insight into the negative $S_\text{ANE}$, we prepared epitaxial thin films of …
