  • 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 ...

  • Intermittent dynamics in externally driven ferroelastics and strain glasses 

    Porta, Marcel; Castán Vidal, Teresa; Lloveras Muntané, Pol Marcel; Saxena, Avadh; Planes Vila, Antoni (American Institute of Physics (AIP), 2018-09-28)
    Article

  • 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 ...

  • Modelling magnetostructural textures in magnetic shape-memory alloys: Strain and magnetic glass behaviour 

    Lloveras Muntané, Pol Marcel; Touchagues, Gilles; Castán, Teresa; Lookman, Turab; Porta, Marcela; Saxena, Avadh; Planes Vila, Antoni (2014-10-01)
    Article
    Restricted access - publisher's policy
    In this paper, we propose a model that combines a Landau free energy part and a micromagnetic free energy part aimed at describing a magnetostructural multiferroic. We show that in the limit of high-elastic anisotropy and ...

  • Modelling shape-memory effects in ferromagnetic alloys 

    Gebbia, Jonathan Fernando; Lloveras Muntané, Pol Marcel; Planes Vila, Antoni; Castán Vidal, Teresa; Saxena, Avadh (Springer, 2015-07-21)
    Article
    Restricted access - publisher's policy
    We develop a combined Ginzburg–Landau/micromagnetic model dealing with conventional and magnetic shape-memory properties in ferromagnetic shape-memory materials. The free energy of the system is written as the sum of ...

  • Multiferroic and related hysteretic behavior in ferromagnetic shape memory alloys 

    Gebbia, Jonathan Fernando; Castán Vidal, Teresa; Lloveras Muntané, Pol Marcel; Porta Tena, Marcel; Saxena, Avadh; Planes Vila, Antoni (2017-08-29)
    Article
    Open Access
    We combine a Ginzburg–Landau model for a ferroelastic transition with the theory of micromagnetism to study the magnetostructural behavior leading to multicaloric effects in ferromagnetic shape memory alloys. We analyze ...

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

    Stern-Taulats, Enric; Gracia-Condal, Adrià; Planes Vila, Antoni; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Tamarit Mur, José Luis; Pramanick, Sabyasachi; Majumdar, Subham; Mañosa Carrera, Lluis (2015-10-12)
    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 ...

  • Tailoring barocaloric and magnetocaloric properties in low-hysteresis magnetic shape memory alloys 

    Stern Taulats, Enric; Planes Vila, Antoni; Lloveras Muntané, Pol Marcel; Tamarit Mur, José Luis; Barrio Casado, María del; Pramanick, Sabyasachi; Majumdar, Subham; Yuce, Suheyla; Emre, Baris; Frontera Beccaria, Carlos; Mañosa Carrera, Lluis (2015-09-01)
    Article
    Open Access
    We report on the barocaloric and magnetocaloric effects in a series of low-hysteresis Ni-Mn-In magnetic shape memory alloys. We show that the behaviour exhibited by several quantities that characterise these caloric effects ...
