Doping as a tuning mechanism for magneto-thermoelectric effects to improve zT in polycrystalline NbP
Eleanor F. Scott, Katherine A. Schlaak, Poulomi Chakraborty +7
Weyl semimetals combine topological and semimetallic effects, making them candidates for interesting and effective thermoelectric transport properties. Here, we present experimenta…
Giant anomalous Nernst signal in the antiferromagnet YbMnBi2
Yu Pan, Congcong Le, Bin He +6
Searching for a high anomalous Nernst effect (ANE) is crucial for thermoelectric energy conversion applications because the associated unique transverse geometry facilitates module…
Large Nernst Power Factor over a Broad Temperature Range in Polycrystalline Weyl Semimetal NbP
Chenguang Fu, Satya N. Guin, Sarah J. Watzman +10
The discovery of topological materials has provided new opportunities to exploit advanced materials for heat-to-electricity energy conversion as they share many common characterist…
Zero-field Nernst effect in a ferromagnetic kagome-lattice Weyl-semimetal Co3Sn2S2
Satya N. Guin, Praveen Vir, Yang Zhang +10
The discovery of magnetic topological semimetals recently attracted significant attention in the field of topology and thermoelectrics. In a thermoelectric device based on the Nern…
Anomalous Nernst effect beyond the magnetization scaling relation in the ferromagnetic Heusler compound CoMnGa
Satya N. Guin, Kaustuv Manna, Jonathan Noky +8
Applying a temperature gradient in a magnetic material generates a voltage that is perpendicular to both the heat flow and the magnetization. This is the anomalous Nernst effect (A…
Effect of magnons on interfacial phonon drag in YIG/metal systems
Arati Prakash, Jack Brangham, Sarah J. Watzman +2
We examine substrate-to-film interfacial phonon drag on typical spin Seebeck heterostructures, in particular studying the effect of ferromagnetic magnons on the phonon-electron dra…
Thermoelectric signatures of the electron-phonon fluid in PtSn4
Chenguang Fu, Thomas Scaffidi, Jonah Waissman +13
In most materials, transport can be described by the motion of distinct species of quasiparticles, such as electrons and phonons. Strong interactions between quasiparticles, howeve…
Thermopower and thermal conductivity in the Weyl semimetal NbP
U. Stockert, R. D. dos Reis, M. O. Ajeesh +7
The Weyl semimetal NbP exhibits an extremely large magnetoresistance (MR) and an ultra-high mobility. The large MR originates from a combination of the nearly perfect compensation…
Extremely high conductivity observed in the triple point topological metal MoP
Nitesh Kumar, Yan Sun, Michael Nicklas +20
Weyl and Dirac fermions have created much attention in condensed matter physics and materials science. Recently, several additional distinct types of fermions have been predicted.…
Magnon-drag thermopower and Nernst coefficient in Fe, Co, and Ni
Sarah J. Watzman, Rembert A. Duine, Yaroslav Tserkovnyak +5
Magnon-drag is shown to dominate the thermopower of elemental Fe from 2 to 80 K and of elemental Co from 150 to 600 K; it is also shown to contribute to the thermopower of elementa…
