Plastic crystals are currently attracting interest because their solid-state caloric functionality could be used to tackle climate change in two critical areas: (i) more environmentally friendly cooling and heating driven by pressure and (ii) passive

Plastic crystals have emerged as benchmark barocaloric (BC) materials for potential solid-state cooling and heating applications due to huge isothermal entropy changes and adiabatic temperature changes driven by pressure. In this work we investigate

Barocaloric materials offer promise in solid-state cooling devices, but few materials have been show to display giant barocaloric effects near room temperature. Here, the authors demonstrate that solid electrolyte AgI displays giant inverse barocalor

We study the barocaloric effect (BCE) in the geometrically frustrated antiferromagnet Mn_{3}NiN across the Néel transition temperature. Experimentally, we find a larger barocaloric entropy change by a factor of 1.6 than that recently discovered in t

The magnetically frustrated manganese nitride antiperovskite family displays significant changes of entropy under hydrostatic pressure that can be useful for the emerging field of barocaloric cooling. Here we show that barocaloric properties of metal
