Anomalous Nernst effect in Pr_0.5Sr_0.5CoO₃

Scattering-independent anomalous Nernst effect in ferromagnets

Using the full-potential linearized augmented plane-wave method within the density functional theory, we compute all contributions to the scattering-independent part of the thermoelectric conductivity tensor α̂, namely, the intrinsic contribution α̂ic and the side-jump contribution α̂sj. For the ferromagnetic materials bcc Fe, hcp Co, fcc Ni, and L10 ordered alloys FePd and FePt, our investigation...

Large anomalous Nernst effect in a skyrmion crystal

Thermoelectric properties of a model skyrmion crystal were theoretically investigated, and it was found that its large anomalous Hall conductivity, corresponding to large Chern numbers induced by its peculiar spin structure leads to a large transverse thermoelectric voltage through the anomalous Nernst effect. This implies the possibility of finding good thermoelectric materials among skyrmion ...

Anomalous-Nernst and anisotropic magnetoresistive heating

Magnetic Nernst effect

The thermodynamics of irreversible processes in continuous media predicts the existence of a magnetic Nernst effect that results from a magnetic analog to the Seebeck effect in a ferromagnet and magnetophoresis occurring in a paramagnetic electrode in contact with the ferromagnet. Thus, a voltage that has DC and AC components is expected across a Pt electrode as a response to the inhomogeneous ...

Quantum Nernst Effect

It is theoretically predicted that the Nernst coefficient is strongly suppressed and the thermal conductance is quantized in the quantum Hall regime of the twodimensional electron gas. The Nernst effect is the induction of a thermomagnetic electromotive force in the y direction under a temperature bias in the x direction and a magnetic field in the z direction. The quantum nature of the Nernst ...
