      Open Access
      There is currently great interest in replacing the harmful volatile hydrofluorocarbon fluids used in refrigeration and air-conditioning with solid materials that display magnetocaloric, electrocaloric or mechanocaloric ...

    • Giant barocaloric effect in all-d-metal Heusler shape memory alloys 

      Aznar Luque, Araceli; Gracia Condal, Adrià; Planes Vila, Antoni; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Tamarit Mur, José Luis; Xiong, Wenxin; Cong, Daoyong; Popescu, C.; Mañosa Carrera, Lluis (American Physical Society (APS), 2019-04-16)
      Article
      Open Access
      We have studied the barocaloric properties associated with the martensitic transition of a shape memory Heulser alloy Ni50Mn31.5Ti18.5 which is composed of all-d-metal elements. The composition of the sample has been ...

    • Giant barocaloric effects at low pressure in ferrielectric ammonium sulphate 

      Lloveras Muntané, Pol Marcel; Stern Taulats, Enric; Barrio Casado, María del; Tamarit Mur, José Luis; Crossley, Sam; Li, Wei; Pomjakushin, Vladimir; Planes Vila, Antoni; Mañosa Carrera, Lluis; Mathur, N.D.; Moya, Xavier (2015-11-01)
      Article
      Open Access
      Caloric effects are currently under intense study due to the prospect of environment-friendly cooling applications. Most of the research is centred on large magnetocaloric effects and large electrocaloric effects, but the ...

    • Giant barocaloric effects over a wide temperature range in the superionic conductor AgI 

      Aznar Luque, Araceli; LLoveras, Pol; Romanini, Michela; Barrio Casado, María del; Tamarit Mur, José Luis; Cazorla Silva, Claudio; Errandonea Ponce, Daniel; Mathur, N.D.; Planes, Antoni; Moya, Xavier; Mañosa Carrera, Lluis (2017-11-29)
      Article
      Open Access
      Current interest in barocaloric effects has been stimulated by the discovery that these pressure-driven thermal changes can be giant near ferroic phase transitions in materials that display magnetic or electrical order. ...

    • Inverse barocaloric effects in ferroelectric BaTiO3 ceramics 

      Stern-Taulats, Enric; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Defay, Emmanuel; Egilmez, Mehmet; Planes Vila, Antoni; Tamarit Mur, José Luis; Mañosa Carrera, Lluis; Mathur, N.D.; Moya Raposo, Xavier (American Institute of Physics (AIP), 2016-09-19)
      Article
      Open Access
      We use calorimetry to identify pressure-driven isothermal entropy changes in ceramic samples of the prototypical ferroelectric BaTiO3. Near the structural phase transitions at ~400 K (cubic-tetragonal) and ~280 K ...

    • Reversible adiabatic temperature changes at the magnetocaloric and barocaloric effects in Fe49Rh51

      Article
      Open Access
      We report on the adiabatic temperature changes (Delta T) associated with the magnetocaloric and barocaloric effects in a Fe49Rh51 alloy, For the magnetocaloric effect, data derived from entropy curves are compared to direct ...

    • Reversible and irreversible colossal barocaloric effects in plastic crystals 

      Aznar Luque, Araceli; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Negrier, Philippe; Planes Vila, Antoni; Mañosa Carrera, Lluis; Mathur, N.D.; Moya Raposo, Xavier; Tamarit Mur, José Luis (Royal Society of Chemistry (RSC), 2020)
      Article
      Open Access
      The extremely large latent heat exchanged in phase transitions involving strong molecular orientational disordering has recently led to the proposal of plastic crystals as a feasible solution for solid-state barocaloric ...
