Summary

Story summary

A study presents the first experimental observation of the transverse Thomson effect, connecting heat, electric current, and magnetic fields.
Researchers observed temperature changes in a bismuth antimony alloy with perpendicular current, heat flow, and magnetic field.
Reversing the magnetic field also reverses the temperature change, differentiating it from the classical Thomson effect.
The findings indicate potential for compact thermal management devices, surpassing traditional thermoelectric modules.
Enhanced Nernst responses in future materials, especially semimetals like WTe2, could produce larger effects.
