119Sn Mössbauer spectroscopy for assessing the local stress and defect state towards the tuning of Ni-Mn-Sn alloys
Unzueta, Iraultza; López García, Javier ; Sánchez-Alarcos Gómez, Vicente ; Recarte Callado, Vicente ; Pérez de Landazábal Berganzo, José Ignacio (AIP Publishing, 2017) Artículo / ArtikuluaThe influence of defects and local stresses on the magnetic properties and martensitic transformation in Ni50Mn35Sn15 is studied at macroscopic and atomic scale levels. We show that both the structural and magnetic properties ... -
Effect of high-energy ball-milling on the magnetostructural properties of a Ni45Co5Mn35Sn15 alloy
López García, José Luis ; Sánchez-Alarcos Gómez, Vicente ; Recarte Callado, Vicente ; Rodríguez Velamazán, José Alberto; Unzueta, Iraultza; García, José Ángel; Plazaola, Fernando; La Roca, Paulo Matías ; Pérez de Landazábal Berganzo, José Ignacio (Elsevier, 2021) Artículo / ArtikuluaThe effect of high-energy ball-milling on the magnetostructural properties of a Ni45Co5Mn35Sn15 alloy in austenitic phase at room temperature has been analyzed by neutron and high-resolution X-ray diffraction. The ball ... -
Identification of a Ni-vacancy defect in Ni-Mn-Z (Z = Ga, Sn, In): an experimental and DFT positron-annihilation study
Unzueta, Iraultza; Sánchez-Alarcos Gómez, Vicente ; Recarte Callado, Vicente ; Pérez de Landazábal Berganzo, José Ignacio ; Zabala, Nerea; García, José Ángel; Plazaola, Fernando (American Physical Society, 2019) Artículo / ArtikuluaBy means of experimental positron-annihilation-lifetime measurements and theoretical density functional theory (DFT) positron-lifetime calculations, vacancy-type defects in Ni50Mn50−xSnx (x = 25, 20, 15, 13, 10) and ... -
Magnetocaloric effect enhancement driven by intrinsic defects in a Ni45Co5Mn35Sn15 alloy
Sánchez-Alarcos Gómez, Vicente ; López García, Javier ; Unzueta, Iraultza; Pérez de Landazábal Berganzo, José Ignacio ; Recarte Callado, Vicente ; Beato López, Juan Jesús ; García, José Ángel; Plazaola, Fernando; Rodríguez Velamazán, José Alberto (Elsevier, 2019) Artículo / ArtikuluaThe influence of mechanically-induced defects on the magnetostructural properties is analyzed in a Ni-Co-Mn-Sn alloy subjected to soft milling and subsequent annealing treatments. It is found that, opposite to what occurs ...
