“…A shift in the martensitic transition by 70 K to higher temperature from T = 240 K (bulk value) to T = 315 K was observed. 22 The inset of Figure 2 The first order nature of the phase transitions was also confirmed by the temperature hysteresis of the heat flow peaks as shown in Figure 2(b). The temperature hysteresis of the heat flow between heating and cooling cycles detected from DSC measurements is consistent with that measured in the M(T) curves (see Figure 2(a)).…”

“…The XRD pattern of the ribbons is similar to that of bulk Ni-Mn-In based Heusler alloys in the phase coexistence region exhibiting a magnetostructural transition near room temperature. 22 Figure 2(a) shows the zero-field-cooling (ZFC), field-cooling (FC), and field-heating (FH) magnetization M(T) curves in a low external low magnetic field (µ o H = 5 mT). The thermal protocol followed to measure each magnetization isotherm through the phase transition was as follows: at zero magnetic field the sample was heated to 400 K to stabilize the austenite phase, cooled to 200 K to form the martensite, and then heated again in no-overshoot mode to the selected measuring temperature, T meas .…”

“…Similar behaviors in the M(µ o H) curves were observed for bulk Ni 50 Mn 35 In 14.25 B 0.75 . 22 The magnetic entropy change (∆S M ) values were estimated from the isothermal magnetization curves near the martensitic transition using a Maxwell relation. 24 Both inverse and direct magnetocaloric effects were observed for bulk and ribbons at the martensitic transition and Curie temperatures, respectively (see Figure 4(a)).…”

The structural, thermal, and magnetic behaviors, as well as the martensitic phase transformation and related magnetocaloric response of Ni50Mn35In14.25B0.75 annealed ribbons have been investigated using room-temperature X-ray diffraction (XRD), differential scanning calorimetry (DSC), and magnetization measurements. Ni50Mn35In14.25B0.75 annealed ribbons show a sharper change in magnetization at the martensitic transition, resulting in larger magnetic entropy changes in comparison to bulk Ni50Mn35In14.25B0.75. A drastic shift in the martensitic transformation temperature (TM) of 70 K to higher temperature was observed for the annealed ribbons relative to that of the bulk (TM = 240 K). The results obtained for magnetic, thermal, structural, and magnetocaloric properties of annealed ribbons have been compared to those of the corresponding bulk alloys.

“…Much research has been focused on Ni-Mn-based Heusler alloys in order to find compositions in which the martensitic transformations occur around room temperature [8][9][10][11][12][13][14][15]. It has been shown that the substitution of Co, Cu, and Al in Ni-Mn-Sn Heusler alloys results in large magnetocaloric effects due to the sudden changes of magnetization and resistance near the martensitic transition temperature [16][17][18].…”

Abstract:The magnetostructural transitions, magnetocaloric effects, and magnetoresistance properties of Ni 45 Mn 43 CrSn 11 Heusler alloys were investigated using X-ray diffraction (XRD), field-dependent magnetization, and electrical resistivity measurements. A large inverse and direct magnetocaloric effect has been observed in Ni 45 Mn 43 CrSn 11 across the martensitic and Curie transition temperature, respectively. The values of the latent heat (L = 15.5 J/g) and corresponding magnetic (∆S M ) and total (∆S T ) entropy changes (∆S M = 35 J/kg·K for ∆H = 5T and ∆S T = 39.7 J/kg·K) have been evaluated using magnetic and differential scanning calorimetry (DSC) measurements, respectively. A substantial jump in resistivity was observed across the martensitic transformation. A large negative magnetoresistance (~67%) was obtained at the magnetostructural transition for a field change of 5 T. The roles of the magnetic and structural changes on the transition temperatures and the potential application of Ni 45 Mn 43 CrSn 11 Heusler alloys for refrigerator technology are discussed.

Various magnetic materials (for example, ferro, ferri, antiferromagnetic) are characterized by their respective transition temperatures (for example, Curie and Néel transitions). Knowledge of these transition temperatures is vital from an application standpoint. Accurate measurements by suitable characterization techniques are needed for identifying these transitions. Several techniques have been used to identify Curie and Néel transition temperatures, with thermal methods being one of the preferred choice. These thermal methods include differential scanning calorimetry (DSC), differential thermal analysis, and thermogravimetric analysis. Although thermal analysis tools have been popularly used for examining magnetic phase transitions, still much confusion exists on their efficacy and might. This review article highlights the strength and limitations of measuring Curie and Néel transitions by thermal techniques; measurements by DSC were the most common choice in previous works. Considering the intrinsic/fundamental nature of these Curie/Néel transitions, such confusion on their measurements (by thermal techniques) and their subsequent analysis (for the order of transition) suggests that a more comprehensive understanding of the events should be an immediate future goal for the research community, at large.
