This device was able to exhibit a transverse thermoelectric effect significantly larger than that produced solely by existing magnetic materials capable of exhibiting the anomalous Nernst effect in the first-ever experimental demonstration of its kind.

This research team demonstrated that a simple layered structure composed of a pair of thermoelectric and magnetic material layers in direct contact was able to produce a significantly larger transverse thermoelectric effect than magnetic materials capable of exhibiting the anomalous Nernst effect when used alone.

"Although Seebeck discovered the thermoelectric effect in common metals more than 200 years ago, nowadays metals are hardly considered as thermoelectric materials because they usually have a very low Seebeck coefficient," explains Fabian Garmroudi, first author of the study.

The thermoelectric effect is based on the movement of charged particles that migrate from the hotter to the colder side of a material.

He thinks the researchers are just measuring the impact of a magnetic field on the well-known thermoelectric effect, in which electrical currents are produced by temperature gradients.
