    • Barocaloric and magnetocaloric effects in Fe49Rh51 

      Stern-Taulats, E.; Planes, Antoni; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Tamarit Mur, José Luis; Pramanick, Sabyasachi; Majumdar, Subham; Frontera, Carlos; Mañosa, Lluís (2014-06-06)
      Article
      Restricted access - publisher's policy
      We report on calorimetry under applied hydrostatic pressure and magnetic field at the antiferromagnetic-ferromagnetic (AFM/FM) transition of Fe49Rh51. Results demonstrate the existence of a giant barocaloric effect in this ...

    • 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. ...

    • Giant solid-state barocaloric effect in the Ni-Mn-In magnetic shape-memory alloy 

      Mañosa, Lluís; Gonzalez Alonso, David; Planes, Antoni; Bonot, Erell; Barrio Casado, María del; Tamarit Mur, José Luis; Aksoy, Seda; Acet, Mehmed (2010-06-01)
      Article
      Open Access
      Solid-state materials showing giant caloric effects near room temperature could provide an alternative to cooling devices based on gas cycles. Strong emphasis has so far been dedicated to caloric effects induced by a ...

    • Ginzburg-Landau modelling of precursor nanoscale textures in ferroelastic materials 

      Planes, Antoni; Lloveras Muntané, Pol Marcel; Castán, Teresa; Saxena, Avadh; Porta, Marcel (2012-11)
      Article
      Restricted access - publisher's policy
      A Ginzburg–Landau free-energy model is proposed to study spatially inhomogeneous states that often occur as precursors of ferroelastic/martensitic transitions. Disorder is included in the harmonic coefficient of the ...

    • Glassy behavior in martensites: Interplay between elastic anisotropy and disorder in zero-field-cooling/field-cooling simulation experiments 

      Lloveras Muntané, Pol Marcel; Castán, Teresa; Porta, Marcel; Planes, Antoni; Saxena, Avadh (2009-08-17)
      Article
      Restricted access - publisher's policy
      We study the combined effect of elastic anisotropy and disorder on the microstructure and thermodynamic behavior in alloys undergoing a martensitic transformation. Within a Ginzburg-Landau free-energy framework we find the ...

    • Influence of elastic anisotropy on structural nanoscale textures 

      Lloveras Muntané, Pol Marcel; Castán, Teresa; Porta, Marcel; Planes, Antoni; Saxena, Avadh (2008-04-25)
      Article
      Restricted access - publisher's policy
      We study the influence of elastic anisotropy on nanoscale precursor textures that exist in some shapememory alloys and show that tweed occurs in the limit of high elastic anisotropy while a nanocluster phase-separated state ...

    • Spatially correlated disorder in self-organized precursor magnetic nanostructures 

      Porta, Marcel; Castán, Teresa; Lloveras Muntané, Pol Marcel; Planes, Antoni; Saxena, Avadh (2007-08-20)
      Article
      Restricted access - publisher's policy
      We study the scaling behavior of the characteristic length of precursor magnetic nanostructures above the Curie temperature with the correlation length of quenched-in disorder. We found that the modulation length of the ...

    • Thermodynamics of stress-induced ferroelastic transitions: Influence of anisotropy and disorder 

      Lloveras Muntané, Pol Marcel; Castán, Teresa; Porta, Marcel; Planes, Antoni; Saxena, Avadh (2010-06-07)
      Article
      Restricted access - publisher's policy
      Stress-induced stress-strain constitutive behavior has been studied in detail in ferroelastic martensites. It has been found that the weights of the long-range anisotropic interactions and of the disorder are important ...
