ABSTRACTThe kinetic arrest of martensitic transformation (MT) has been observed in as-solidified Ni52.2Mn34.3In13.5 melt spun ribbons. The main characteristics of this unusual field-induced magneto-structural phenomenon have been determined through a dc magnetization study. The sample studied was fabricated by rapid solidification using the melt spinning technique at a high quenching rate of 48 ms-1. At room temperature, it is a single phase austenite (AST) with the bcc B2-type crystal structure and Curie temperature of TCA=285 K. With decreasing temperature, the austenite phase transforms into the martensite phase (MST) with TCM≈185 K at a starting martensitic transition temperature of MS=275 K. A moderate but progressive kinetic arrest of the AST to MST transformation has been observed for magnetic field values above H=10 kOe and was studied up to Hmax= 90 kOe. The metastable character of the non-equilibrium field-cooled state is revealed by the decreasing behavior of the saturation magnetization under a large magnetic field of 50 kOe after temperature cycling from 10 K to 150 K. The total magnetization difference Δσ between the zero field-cooling and field-cooling pathways of the temperature dependence of magnetization shows irreversible and reversible components and the former decreases with decreasing temperature.

We report on the influence of short annealing treatments at 923 K and 1073 K during 10min on both martensitic transformation and exchange bias effect for the Ni50.0Mn36.5Sn13.5Heusler alloy ribbon by means of magnetic measurements. We have observed that the martensitic transformation is shifted towards higher temperatures with increasing annealing temperature. Furthermore, isothermalM(H)hysteresis loops performed under field-cooling protocol show an exchange bias effect for as-quenched and two annealed ribbons, which indicates the existence of ferromagnetic-antiferromagnetic interactions at low temperatures. In particular, we observe thatHCdiminishes with the increasing of the annealing temperature, butHEis not affected by the heat treatment.
