Intrinsic nonlinear Nernst and Seebeck effect

New Journal of Physics
The Nernst and Seebeck effects are crucial for thermoelectric energy harvesting. However, the linear anomalous Nernst effect requires magnetic materials with intrinsically broken time-reversal symmetry.

Effect of bismuth crystal orientation in Nernst thermomagnetic devices

AIP Advances
In this work we report Nernst effect measurements in single crystal bismuth samples, with special emphasis on the characterization of the Nernst coefficient when the magnetic field, heat current and generated voltage are aligned along specific directions

Large anomalous Nernst effect in a skyrmion crystal. [PDF]

Sci Rep, 2016
AbstractThermoelectric 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.

Quasiparticle Nernst Effect in Stripe-Ordered Cuprates [PDF]

Physical Review B, 2012
Experiments on underdoped cuprate superconductors suggest an intricate relation between the normal-state Nernst effect and stripe order: The Nernst signal appears enhanced near \(\frac{1}{8}\) hole doping and its onset temperature scales with the stripe ...

Gapped nodal planes and large topological Nernst effect in the chiral lattice antiferromagnet CoNb3S6 [PDF]

Nature Communications
The electronic structure of compensated antiferromagnets (CAF) creates large functional responses, reminiscent of ferromagnets and suitable for data storage and readout, despite (nearly) net-zero spontaneous magnetization. Many experimental signatures of

Intrinsic Anomalous Nernst Effect Amplified by Disorder in a Half-Metallic Semimetal

Physical Review X, 2019
Intrinsic anomalous Nernst effect, like its Hall counterpart, is generated by Berry curvature of electrons in solids. Little is known about its response to disorder.
