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 AccessWe 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 policyIn 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 policyWe 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 ... -

Article
Open AccessWe 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 ... -
