    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. ...

  • Relationship between the two-component system 1-Br-adamantane + 1-Cl-adamantane and the high-pressure properties of the pure components 

    Barrio Casado, María del; Levit Valenzuela, Rafael; Lloveras Muntané, Pol Marcel; Aznar Luque, Araceli; Negrier, Philippe; Mondieig, Denise; Tamarit Mur, José Luis (2018-03-15)
    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
    Restricted access - publisher's policy
    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 ...
