WebAbstract. The extension of magnon electron drag (MED) to the paramagnetic domain has recently shown that it can create a thermopower more significant than the classical … WebOct 14, 2024 · This effect is called "paramagnon drag thermopower" and can convert the temperature difference into electrical energy. This discovery helps to collect heat more efficiently, for example, by converting heat from the car's exhaust into electricity, improving fuel efficiency, or powering smart clothing through body heat.

WebSep 19, 2024 · The research team tested the concept of paramagnon drag thermopower by heating lithium-doped MnTe to approximately 250 degrees Celsius above its Néel temperature (34 degrees Celsius) - the temperature at which the spins in the material lose their long-range magnetic order and the material becomes paramagnetic. Webcaloritronic effects, such as spin-Seebeck, 1 magnon-drag,2,3 magnon-bipolar drag,4 paramagnon-drag,5 and spin-entropy6 effects. Over the past two decades, the progress in thermoelectric research has been primarily dominated by finding methods for reducing the thermal conductivity of the materials,such as increasing the phonon scattering dishwasher 30 height

Webtion to thermopower in MnTe far above the Néel temperature was reported, which was associated with the paramagnon-drag effect [3,4,13,14]. Like magnon and paramagnon drag, spin entropy and spin fluctuation in a system has also led to significant enhancement of the thermopower [5–8]. *[email protected] WebSep 1, 2024 · Paramagnon drag in high thermoelectric figure of merit Li-doped MnTe.
