      Article
      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 and reversible inverse barocaloric effects near room temperature in ferromagnetic MnCoGeB0.03 

      Aznar Luque, Araceli; Lloveras Muntané, Pol Marcel; Kim, Jiyeob; Stern Taulats, Enric; Barrio Casado, María del; Tamarit Mur, José Luis; Mathur, N.D.; Moya Raposo, Xavier (2019-09-13)
      Article
      Open Access
      Hydrostatic pressure represents an inexpensive and practical method of driving caloric effects in brittle magnetocaloric materials, which display first-order magnetostructural phase transitions whose large latent heats are ...
    • 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 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. ...

      Article
      Open Access
      The temperature-composition phase diagram of the two-component system 1-Br-adamantane and 1-Cl-adamantane has been determined by means of thermal analysis techniques and X-ray powder diffraction from the low-temperature ...
    • 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 ...
