Outline

Thermomagnetic effects in magnets, where an electric field is generated perpendicular to a thermal gradient, are potentially useful for next-generation energy harvesting. However, to date, the magnitude of thermomagnetic voltage has been negligibly small in most materials. In this project, I will explore new layered magnets hosting massless Dirac fermions, which are predicted to exhibit giant thermomagnetic effects. By synthesising them with extreme conditions, such as high pressure and vacuum, I will experimentally unveil the fundamental physics of novel thermomagnetic phenomena associated with Dirac fermions, aiming at developing new power-generating technology.
