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 ...
