The inverse magnetocaloric effect (MCE) in Ni-Mn-based Heusler compounds occurs during the magnetostructural transition between low-temperature, low-magnetization martensite and hightemperature, high-magnetization austenite. In this study, we analyze the metamagnetic transformation of a Ni 49.8 Mn 35 In 15.2 compound by simultaneous adiabatic temperature change ΔT ad and strain Δl/l 0 measurements in pulsed magnetic fields up to 10 T. We observe a ΔT ad of -10 K and a Δl/l 0 of -0.22 % when the reverse martensitic transition is fully induced at a starting temperature of 285 K. By a variation of the magnetic field-sweep rates between 316 Ts -1 , 865 Ts -1 and 1850 Ts -1 , the transitional dynamics of the reverse martensitic transformation have been investigated. Our experiments reveal an apparent delay upon the end of the reverse martensitic transformation at field rates exceeding 865 Ts -1 which is related to the annihilation of retained martensite. As a consequence, the field hysteresis increases and higher fields are required to saturate the transition. In contrast, no time-dependent effects on the onset of the reverse martensitic transformation were observed in the studied field-sweep range. Our results demonstrate that kinetic effects in Heusler compounds strongly affect the magnetic cooling cycle, especially when utilising a multicaloric "exploiting-hysteresis cycle" where high magnetic fieldsweep rates are employed.

Nowadays, ferromagnetic shape memory Heusler alloys are ones of famous multifunctional materials exhibiting many interesting features in the temperature interval of the martensitic transformation due to the strong interrelation between crystal structure and magnetic order. The multiferroic, magnetoresistive, martensitic and related magnetic shape-memory behavior as well as magnetocaloric properties are examples of these unique features. Generally, tuning of both structural and magnetic transition temperatures can be useful to achieve better functional properties. Today, the optimization problem of Heusler compounds is of a great importance. In this chapter, we review the most important features of ternary and quaternary ferromagnetic shape memory Ni-Mn-In and Ni-Mn-In-Z materials, which are experimentally and theoretically obtained in the last three years. We discuss the experiments devoted to the study of phase diagrams, thermomagnetizations, magnetic field and stress induced strains, magnetoresistance and magnetocaloric effects. The theoretical investigations of magnetic and structural properties are reviewed in the framework of the phenomenological approach, first-principles and Monte Carlo methods.

“…Moreover, rapid quenching from the liquid state can modify the atomic ordering of the ribbons and the MT behavior, and it is a very effective way to synthesize these samples avoiding or reducing annealing time. Up to now, some Ni–Mn–X ribbons have been reported and their MT and magnetic properties were investigated consequently . However, as far as we know, there are few reports about the Ni–Mn–V–Sn ribbons.…”

“…Since magnetic‐field‐induced shape memory effect was reported in the Ni–Co–Mn–In FSMAs, great efforts have been made to induce the reverse MT by applying a magnetic field . The change in MT temperature (Δ T ) in response to the change in magnetic field (Δ H ) can be approximately given by the Clausius–Clapeyron relation, Δ T/ Δ H = Δ M/ Δ S , where Δ M and Δ S are differences in magnetization and entropy between the austenitic and martensitic phases.…”

“…In addition, introduction of a fourth element, such as Fe, Cu, or some interstitial atoms, has been widely used to tailor transition temperatures and Δ M associated with the MT in these alloys . Recently, there have been some reports on Ni–Mn–X as‐quenched ribbons, which were prepared by melt spinning . Compared with the bulk alloys, these ribbons can directly reach a homogeneous single phase with the ordered columnar grains growing perpendicularly to the ribbon plane.…”

The rapidly solidified Ni41.98Mn42.97V2.08Sn12.97 ribbons are prepared by the melt‐spinning technique. The microstructure, martensitic transformation (MT), and magnetocaloric effect of the ribbons are greatly affected by annealing treatment. The equiaxed crystallized grains with the relatively homogeneous size distribution are observed for these ribbons. After annealing, the grain size becomes obviously large, the lattice constants decreases, and the exchange bias effect gets improved. The MT temperatures increase obviously for the annealed ribbons. Large magnetic entropy change (ΔS) is obtained in the annealed Ni–Mn–V–Sn ribbons. The peak values of ΔS in the annealed ribbons are 41.6 and −2.3 J kg−1 K−1 in the vicinity of MT temperature and Curie temperature of austenite, respectively, for the field change of 30 kOe.
