Summary: The Ni-Mn-Co-Sn based Heusler alloys have attracted attention due to their significant magnetocaloric and magnetoresistance properties near the magneto-structural martensite transformation. The Ni45Mn39Co5Sn11 bulk Heusler alloy exhibited large magnetic entropy changes and refrigeration capacity values across the MT regime, showing promise for magnetocaloric applications. Additionally, the influence of martensite-austenite phase fractions on magnetoresistance properties was investigated, establishing a strong correlation between transformed austenite phase fraction and magnetoresistance.

Summary: This study investigates the Curie transition of austenitic Ni-Mn-In full Heusler compounds by replacing Mn atoms with Fe or Cu. It is found that Fe and Cu modify the magnetic moments and interactions, resulting in changes in the Curie temperature and saturation magnetization of the compound. The study successfully synthesizes quinary compounds with tunable Curie temperature and high saturation magnetization, highlighting a promising strategy for designing regenerators for room temperature magnetocaloric applications.

Summary: In this study, the magnetocaloric and magnetoresistance properties of Fe-doped Ni-Mn-Sn-Fe alloy during a metamagnetic structural transition were investigated. The alloy exhibited intermartensite phase after annealing, leading to multiple abrupt magnetization and resistivity changes during the heating process of martensite transformation. The results showed continuous magnetic entropy change peaks and large negative magnetoresistance under 5.0 T.

Summary: This article presents the magnetocaloric effect of electrodeposited Ni-Mn-Ga-based Heusler nanowires using the indirect approach. The nanowires exhibit a martensitic transformation capability above room temperature, resulting in a high magnetic entropy change of >2.5 J.kg-1.K-1. The analysis reveals a maximum magnetic entropy change at a moderate magnetic field of only 2 T. The cheap fabrication method and strong magnetocaloric response of the nanowires open up new possibilities in the field of nanosized Heusler alloys as refrigerants, actuators, or sensors.

Summary: In this study, a Cu doped NiMnInCo metamagnetic shape memory alloy with low thermal hysteresis and high cooling capacity was designed. The induced L21 ordering process enhanced the magnetization of the austenite without affecting the transformation temperatures, resulting in improved magnetocaloric effect, reversibility, and refrigeration capacity.

Summary: The effect of Si substitution on the Mn site in Ni47Mn40-xSixIn13 alloy was investigated for its structure, electrical, magnetic, and magnetocaloric properties. Increasing Si content lowered both the Curie transition and martensitic phase transition temperatures, leading to exchange bias phenomenon at lower temperatures. The maximum magnetic entropy change decreased with higher Si content, indicating a decrease in magnetocaloric effect.

Summary: The research revealed that two Heusler compounds, Ni2Mn0.75Cu0.25Ga0.84Al0.16 and Ni2Mn0.70Cu0.30Ga0.84Al0.16, exhibit different magnetic properties and magnetocaloric effects during magnetic field changes. Ni2Mn0.75Cu0.25Ga0.84Al0.16 shows a significant magnetocaloric effect during the transition between magnetically aligned structures, while Ni2Mn0.70Cu0.30Ga0.84Al0.16 demonstrates high entropy change at room temperature.

Summary: The Ni46Mn41In13 (close to 2-1-1 system) Heusler alloy was investigated through magnetization measurement at varying temperatures and magnetic fields. The magnetocaloric effect was found to have a maximum increment T-ad of -4.2 K at a temperature of 212 K and a magnetic field of 10 T during the martensitic transformation. The alloy's structure was examined using transmission electron microscopy (TEM) and revealed concentration stratification occurring through spinodal decomposition into nanoscale regions, along with the presence of martensitic and austenitic phases depending on temperature and sample thickness.

Summary: All-d-metal Ni(Co)-Mn-Ti Heusler alloys exhibit high magnetocaloric/barocaloric effects due to the occurrence of a martensitic transformation and excellent mechanical properties. By partially substituting Mn with Fe or Cr, the martensitic transition and magnetocaloric response can be further regulated. Cr doping increases the entropy change but reduces the magnetization difference, while Fe doping reduces the entropy change but maintains the magnetization difference. The Fe-doped alloy requires lower magnetic fields to initiate the transformation and shows higher and broader isothermal entropy change peaks.

Summary: Ni 43Mn 46Sn11-xTex(x = 0.1, 0.2, 0.3, 0.4, 0.5, 1) alloys were prepared by arc melting. Structural studies revealed the presence of L21 cubic austenite phase. The martensite phase and lattice constant decrease with increasing Te concentration. All alloys exhibit first-order phase transition. The martensite temperature increases successively with increasing Te concentration. A non-linear magnetic entropy change and thermal hysteresis were observed with increasing Te concentration. The magnetocaloric effect was observed over a broad temperature range by varying the Te concentration. The tunable martensite temperature and magnetocaloric properties with Te concentration make these alloys useful for magnetic refrigeration applications.

Summary: This study investigated the effect of hydrostatic pressure on the magnetostructural transition (MST) in an isostructurally alloyed compound, and found that pressure can induce a structural transition more abruptly than purely magnetically induced phase transition, leading to an increase in isothermal entropy change drastically. Due to the large volume change and structural breakdown at MST, an indirect method was used to estimate adiabatic temperature change.

Summary: The nature of phase transition and the reversibility of the magnetocaloric effect have been studied in MnNi1-xCoxGe0.97Al0.03. The introduction of Al substitution lowers the structural phase transition temperature, resulting in a coupled first-order magnetostructural transition. A composition-dependent triple point has been observed in the system, where the first-order phase transition splits into an additional phase boundary with a second-order transition character at higher temperature. The reversibility of the low-field entropy change is enhanced at the triple point due to lattice softening and larger field-induced structural entropy change.
