Sánchez Llamazares Física, Astronomía y Matemáticas Ni Mn melt spun ribbons In ferromagnetic shape memory alloys Kinetic arrest (KA) of martensitic transformation (MT) has been observed in as-solidified Ni 52 . 2 Mn 34 . 3 In 13 . 5 melt-spun ribbons; a charac- terization by dc magnetization measurements was carried out. These alloy ribbons transform martensitically from a single austenitic (AST) parent phase with B2-type crystal structure. For an applied magnetic field μ 0 H of 1 T and up to 9 T, a moderate but progressive KA of the MT is observed. The metastability of the non-equilibrium field-cooled glassy state was characterized by introducing thermal and magnetic field fluctuations. It was found that the total magnetization difference ( ∆ σ ) between the zero field-cooling (ZFC) and field-cooling (FC) pathways of the temperature dependence of magnetization ∆ σ ( T ) shows irreversible and reversible components; the former decreases as the temperature decreases. After a short thermal annealing of 10 min at 1073 K AST shows a highly ordered L2 1 -type crystal structure and the kinetic arrest of martensitic transformation is no longer observed suggesting a connection between the crystal structure order of austenite and the appearance of the kinetic arrest phenomenon. 2017 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57051630006 es http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
