Nernst effect in the electron-doped cuprates
We calculate the normal state Nernst signal in the cuprates resulting from a reconstruction of the Fermi surface due to spin density wave order. An order parameter consistent with the reconstruction of the Fermi surface detected in electron-doped materials is shown to sharply enhance the Nernst signal close to optimal doping. Within a semiclassical treatment, the obtained magnitude and position...
متن کاملMagnetic 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 ...
متن کاملQuantum 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 ...
متن کاملNernst Effect in Electron-doped Pr 2−x Ce X Cuo 4
The Nernst effect of Pr 2−x Ce x CuO 4 (x=0.13, 0.15, and 0.17) has been measured on thin film samples between 5-120 K and 0-14 T. In comparison to recent measurements on hole-doped cuprates that showed an anomalously large Nernst effect above the resistive T c and H c2 [1–4], we find a normal Nernst effect above T c and H c2 for all dopings. The H c2 (T) determined from the Nernst effect shows...
متن کاملScattering-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...
