“…2(a). Consequently, a T hys of 2.3 K is achieved for the sample with x = 0.3, which is extremely small in comparison with other Ni-Mn-X-based Heusler alloys [12][13][14][15][16][20][21][22][23][24][25][26][27][28][29][31][32][33][34]. Due to the optimization of the hysteresis, the sample can resist the large migration of T t under thermal cycles.…”

“…For magnetic SMAs, the strong correlation between the hysteresis width and λ 2 has been widely reported in Ni-Mn-X-based Heusler alloys [15,16,27,33,49,55,56]. The determination of λ 2 relies on the crystalline structures of austenite and martensite and their lattice parameters [57].…”

“…From this tensor the eigenvalues are calculated: λ 1 = 0.9476(2), λ 2 = 1.0017 (5), and λ 3 = 1.0395(4) where λ 1 < λ 2 < λ 3 . Compared with other Heusler alloys [15,16,27,33,49,55,56], the sample with x = 0.3 exhibits a smaller value of |1 − λ 2 | = 1.7(5) × 10 −3 , which indicates a good geometric compatibility between the two phases. As a result, a small T hys can be obtained, in agreement with the model prediction.…”

“…Both experimental approaches and theoretical calculations have confirmed that a giant MCE can be expected in materials where the magnetism and the crystalline structure strongly couple [5,6]. Nowadays, a number of promising candidate materials for room-temperature MR have been proposed, including (Mn,Fe)(P,X)-based compounds (X = As, Ge, Si) [7][8][9], La(Fe, Si) 13 -based materials [10,11], Ni-Mn-X based Heusler alloys (X = In, Sn, Sb) [12][13][14][15][16], and the Mn(Co,Ni)(Ge,Si) system [17][18][19].…”

“…Ni-Mn-X based Heusler alloys, in which the lattice structure consists of four interpenetrating fcc sublattices, exhibit a magnetostructural transition (MST) from the ferromagnetic cubic austenite to the weakly magnetic martensite with a lower symmetry [12][13][14][15][16][20][21][22]. Due to the coupling of ferromagnetism and ferroelasticity, multifunctional effects, such * Corresponding authors: J.Liu-7@tudelft.nl; xufeng@njust.edu.cn as caloric effects, magnetostrain effect, and magnetoresistance can be triggered under external stress or magnetic field [12][13][14][15][16][23][24][25][26][27]. From the viewpoint of the MCE, the entropy changes of the lattice and the magnetism mainly contribute to the total entropy change ( S t ) during the martensitic transition [28,29].…”

Ni-Mn-X (X = In, Sn, and Sb) based Heusler alloys show a strong potential for magnetic refrigeration owing to their large magnetocaloric effect (MCE) associated with first-order magnetostructural transition. However, the irreversibility of the MCE under low field change of 0-1 T directly hinders its application as an efficient magnetic coolant. In this work, we systematically investigate thermal and magnetic properties, crystalline structure and magnetocaloric performance in Ni 51−x Mn 33.4 In 15.6 V x alloys. With the introduction of V, a stable magnetostructural transition near room temperature is observed between martensite and austenite. An extremely small hysteresis of 2.3 K is achieved for the composition x = 0.3. Due to this optimization, the magneticfield induced structural transition is partially reversible under 0-1 T cycles, resulting in a reversible MCE. Both magnetic and calorimetric measurements consistently show that the largest value for the reversible magnetic entropy change can reach about 5.1 J kg −1 K −1 in a field change of 0-1 T. A considerable and reversible adiabatic temperature change of −1.2 K by the direct measurement is also observed under a field change of 0-1.1 T. Furthermore, the origin of this small hysteresis is discussed. Based on the lattice parameters, the transformation stretch tensor is calculated, which indicates an improved geometric compatibility between the two phases. Our work greatly improves the MCE performance of Ni-Mn-X-based alloys and make them suitable as realistic magnetic refrigeration materials.

Engineering the martensite–austenite transformation interval (ΔT i) is important for optimizing the functionalities of metamagnetic shape memory alloys. Although it has been revealed that both doping and thermal annealing can influence ΔT i, the underlying mechanisms remain largely unexplored. Herein, a direct observation of the martensitic transformation process in Ni45Co5Mn37In13 alloys with distinct ΔT is is made. In contrast to the typical burst‐like martensitic transition, it is revealed that the alloy with a large ΔT i exhibits discretely distributed martensitic and austenite phases that evolve slowly with varying temperature. The unusual properties are found to be mainly correlated with atomic disorder rather than lattice distortions. The results indicate the great potential of atomistic engineering in manipulating the martensitic transformation for applications.

Metamagnetic shape memory alloys (MMSMAs) are attractive functional materials owing to their unique properties such as magnetostrain, magnetoresistance, and the magnetocaloric effect caused by magnetic‐field‐induced transitions. However, the energy loss during the martensitic transformation, that is, the dissipation energy, Edis, is sometimes large for these alloys, which limits their applications. In this paper, a new Pd2MnGa Heusler‐type MMSMA with an extremely small Edis and hysteresis is reported. The microstructures, crystal structures, magnetic properties, martensitic transformations, and magnetic‐field‐induced strain of aged Pd2MnGa alloys are investigated. A martensitic transformation from L21 to 10M structures is seen at 127.4 K with a small thermal hysteresis of 1.3 K. The reverse martensitic transformation is induced by applying a magnetic field with a small Edis (= 0.3 J mol−1 only) and a small magnetic‐field hysteresis (= 7 kOe) at 120 K. The low values of Edis and the hysteresis may be attributed to good lattice compatibility in the martensitic transformation. A large magnetic‐field‐induced strain of 0.26% is recorded, indicating the proposed MMSMA's potential as an actuator. The Pd2MnGa alloy with low values of Edis and hysteresis may enable new possibilities for high‐efficiency MMSMAs.
