Influence of annealing on magnetic field-induced structural transformation and magnetocaloric effect in Ni–Mn–In–Co ribbons

Crystal structure determination of incommensurate modulated martensite in Ni–Mn–In Heusler alloys

“…To date, the crystal structures of martensite phases in Ni-Mn-In alloys have largely been investigated by means of X-ray diffraction (XRD), selected area electron diffraction (SAED) and neutron diffraction (ND) [7][8][9][10][11][12][13][14][15][16][17][18][19]. For easy consultation, some results reported in the literature are summarized in Table 1.…”

Effects of Co Additions on the Martensitic Transformation and Magnetic Properties of Ni–Mn–Sn Shape Memory Alloys

“…With the decreasing temperature, these alloys undergo a first-order martensitic transformation (MT) from a high symmetry phase (austenite) to a low symmetry phase (martensite) along with the change of magnetization. Having developed the Ni-Mn-based FSMA, both bulk samples and melt-spun ribbons have been extensively investigated, and therefore, the melt-spinning technique has been widely regarded as an effective method to synthesize highly textured polycrystalline FSMA [6][7][8][9]. It is well known that the magnetic and martensitic transition can be tuned markedly by the partial substitution of Co for Ni into those Mnrich Ni-Mn-X (Sn, In, Sb) alloys.…”

Structural and Magnetic Properties of Magnetic Shape Memory Alloys on Ni-Mn-Co-In Self-standing Films

“…On the other hand, the temperature hysteresis decreases with high-temperature heat treatment. The increase in the crystal particle size (Vishnoi and Kaur 2010), removal of defects, and the relaxation of the internal stress (Liu et al 2009) decrease a phase transition suppression factor. From the result obtained in this study, sufficient homogenization heat treatment for the Ni-Co-Mn-In sputtering film decreases the transition temperature hysteresis while increasing the martensitic transition temperature ( Table 2).…”
