    • Acoustic emission avalanches during compression of granular manganites 

      Soto-Parra, Daniel Enrique; Vives, Eduard; Botello Zubiate, Maria Eugenia; Matutes Aquino, José Andrés; Planes, Antoni (American Institute of Physics, 2018)
      "We have studied acoustic emission (AE) during compression of La0.8Ca0.28Sr0.08MnO2.7 manganites with different microstructures obtained by selected synthesis techniques. In ceramic samples with large grains obtained by a ...

    • Caloric effects induced by magnetic and mechanical fields in a Ni50Mn25-xGa25Cox magnetic shape memory alloy 

      Castillo Villa, Pedro Osmany; Soto-Parra, Daniel Enrique; Matutes Aquino, José Andrés; Ochoa-Gamboa, Raul Armando; Planes, Antoni; Mañosa, Lluis; González Alonso, David; Stipcich, Marcelo; Romero, Ricardo; Ríos Jara, David; Flores Zúñiga, Horacio (2011-05)
      "We have studied the elastocaloric effect in a Co-doped Ni-Mn-Ga magnetic Heusler shape memory alloy in the vicinity of its martensitic transition. Measurements of the length change as a function of temperature have been ...

    • Elastocaloric and magnetocaloric effects in Ni-Mn-Sn(Cu) shape-memory alloy 

      Castillo Villa, Pedro Osmany; Mañosa, Lluis; Planes, Antoni; Soto-Parra, Daniel Enrique; Sánchez Llamazares, José Luis; Flores Zúñiga, Horacio; Frontera, Carlos (2013-02)
      "We have studied magnetocaloric and elastocaloric properties of a Ni-Mn-Sn(Cu) metamagnetic shape-memory alloy undergoing a magneto-structural transition (martensitic type) close to room temperature. Changes of entropy ...

    • Elastocaloric effect in Ti-Ni shape-memory wires associated with the B2 ↔ B19' and B2 ↔ R structural transitions 

      Soto-Parra, Daniel Enrique; Vives, Eduard; Mañosa, Lluis; Matutes Aquino, José Andrés; Flores Zúñiga, Horacio; Planes, Antoni (2016-02)
      "We have studied the elastocaloric properties of Ti-Ni shape-memory wires subjected to specific heat treatments to decouple the B2 <-> R transition from the B2 <-> B19' one. The entropy values at moderate stresses (similar ...

    • Large and reversible elastocaloric effect near room temperature in a Ga-doped Ni–Mn–In metamagnetic shape-memory alloy 

      Camarillo García, Juan Pablo Ramón; Aguilar Ortiz, Christian Omar; Flores Zúñiga, Horacio; Ríos Jara, David; Soto-Parra, Daniel Enrique; Stern Taulats, Enric; Mañosa, Lluis; Planes, Antoni (2017-02)
      "We report a giant elastocaloric effect near room temperature in a polycrystalline Ga-doped Ni-Mn-In ferromagnetic shape-memory alloy. The elastocaloric effect has been quantified by measuring both isothermal stress-induced ...

    • Magnetocaloric effect in the low hysteresis Ni-Mn-In metamagnetic shape-memory Heusler alloy 

      Castillo Villa, Pedro Osmany; Mañosa, Lluis; Frontera, Carlos; Majumdar, Subham; Planes, Antoni (2014-05)
      "We have studied magnetocaloric properties of a Ni-Mn-In metamagnetic shape-memory alloy especially designed in order to display low thermal hysteresis. Magnetization and calorimetric measurements under a magnetic field ...

    • Statistical similarity between the compression of a porous material and earthquakes 

      Baró, Jordi; Corral, Alvaro; Illa, Xavier; Planes, Antoni; Salje, Ekhard K. H.; Schranz, Wilfried; Soto-Parra, Daniel Enrique; Vives, Eduard (2013-02)
      "It has long been stated that there are profound analogies between fracture experiments and earthquakes; however, few works attempt a complete characterization of the parallels between these so separate phenomena. We study ...
