    • 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 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 ...
