“…In addition, positive pressure dependence of the Curie temperature has been reported by Kaneko et al [26] and Kanomata et al [25]. Since the reports of the occurrence of the martensitic transformation in the off-stoichiometric composition [1], a large number of investigations have been performed and many interesting physical properties have been reported in Ni-Mn-Sb and Co-substituted Ni-Co-Mn-Sb alloys, such as large magnetoresistance [27,28], a negative magnetocaloric effect [29,30], a metamagnetic shape memory effect [31] and exchange biasing behavior [32,33], similar to properties of other NiMn-based alloys. In order to investigate metamagnetic behavior and magnetic moment of the field-induced parent phase of Ni-Co-Mn-Sb alloy, magnetization experiments up to a static magnetic field of 18 T and a pulsed magnetic field of 40 T were performed.…”

Abstract:In order to investigate behavior of magnetic field-induced reverse martensitic transformation for Ni-Co-Mn-Sb, magnetization experiments up to a static magnetic field of 18 T and a pulsed magnetic field of 40 T were carried out. In the thermomagnetization curves for Ni41Co9Mn39Sb11 alloy, the equilibrium transformation temperature T0 was observed to decrease with increasing applied magnetic field, μ0H, at a rate of dT0/dμ0H = 4.6 K/T. The estimated value of entropy change evaluated from the Clausius-Clapeyron relation was about OPEN ACCESSMetals 2014, 4 610 14.1 J/(K· kg), which was in good agreement with the value obtained by differential scanning calorimetric measurements. For the isothermal magnetization curves, metamagnetic behavior associated with the magnetic field-induced martensitic transformation was observed. The equilibrium magnetic field, μ0H0 = (μ0HAf + μ0HMs)/2, of the martensitic transformation tended to be saturated at lower temperature; that is, transformation arrest phenomenon was confirmed for the Ni-Co-Mn-Sb system, analogous with the Ni(Co)-Mn-Z (Z = In, Sn, Ga, Al) alloys. Temperature dependence of the magnetic field hysteresis, μ0Hhys = μ0HAf − μ0HMs, was analyzed based on the model for the plastic deformation introduced by the dislocations. The behavior can be explained by the model and the difference of the sweeping rate of the applied magnetic field was well reflected by the experimental results.

“…13 Magnetic field (H) versus temperature of Ni 45 Co 5 Mn 36.7 In 13.3 sample during adiabatic magnetization processes in pulsed magnetic fields. Inset: directly measured adiabatic temperature change (DT ad ) (15 T) and that calculated from isothermal magnetization curves (DT MH ) shown as a function of temperature Ni 45 Co 5 Mn 38 Sb 12 , the resistivity significantly increases and the magnetization decreases due to the microstructural deformation and lattice disorder [93]. Sahoo et al [94] compared the magnetic properties, MR, and MCE of asspun ribbon with the annealed ribbon and the bulk alloy of Ni 46 Co 4 Mn 38 Sb 12 , and observed that T M of as-spun ribbon is higher than that of the bulk sample, while the magnetization of as-spun ribbon is lower.…”

Magnetic shape memory alloys (MSMAs), both in condensed matter physics and in material science, are one of the most extensive research subjects. They show prompt response to the external magnetic field and give rise to large strain and have fine reversibility. The well-known example is Heusler-type MSMAs, which possess excellent multifunctional properties and have potential applications in energy transducer, actuator, sensor, microelectromechanical system, and magnetic refrigerator. In this paper, it is shown the recent progress in magnetostructural transformation, magnetic properties, shape deformation, magnetocaloric effect as well as magnetic field-induced shape memory effect in Ni-Mn-Ga, NiMnZ (Z = In, Sn, Sb), and NiCoMnZ (Z = In, Sn, Sb, Al) Heusler-type MSMAs. The remaining issues and possible challenges are briefly discussed.

“…However, no detailed studies were reported on microstructure and in-situ phase transformation studies both in bulk and ribbon forms. Further, in our recent published work on NieMneSb alloys, the irreversible nature of transport, magnetic and thermal properties upon repeated martensitic transitions has been attributed to the possible changes in the microstructure [24]; however, we have not investigated the microstructural aspects as a function of temperature. Hence, considering the lack of sufficient microstructural data as a function of temperature, it would be of great scientific interest to understand the microstructure and insitu phase transformation behavior in NieMn based alloys.…”
