Cover Story: The multicaloric effect is defined as the adiabatic temperature change in multiferroic materials induced by the application of an external excitation such as an electric field, magnetic field or mechanical stress, as first proposed by Vopson in 2012. Depending on the operating conditions, the temperature changes can be positive or negative, leading to the possible commercialisation of the multicaloric effect in solid-state heating or cooling systems. The featured cover article briefly reviews the already known solid-state cooling process based on the multicaloric effect, and it describes its new possible application to solid-state heating. The cover image shows the schematic diagrams of the multicaloric cooling and heating cycles, their corresponding thermodynamic cycles and the generalised multicaloric effect equation governing these processes. View this paper
