Cool multiferroic materials for solid-state cooling
The solid-state refrigeration technology is currently dominated by cryogenic cooling for space applications and other high-end metrologies or applications requiring ultra-low (mK - mK) temperatures.
To date, one of the most efficient ways of achieving ultra-low cryogenic temperatures is based on the solid-state cooing via the magneto-caloric effect. Other solid-state caloric cooling effects such as electro-caloric or elasto-caloric cooling have been demonstrated, but these are in their infancy and the thermal changes are inferior to those of magneto-caloric materials.
In this lecture I will present substantial developments in condensed matter physics by introducing theoretically the 'multicaloric effect', a new caloric effect that occurs in multiferroic solids.
It is demonstrated this new caloric effect offers significant improvements relative to the existing ones, and it could impact not only the ultra-low cryogenics cooling sector, but it could also make room temperature solid-state cooling technology more feasible for commercialisation.
