“…This behavior is assumed to be related to the structural changes that occur near T C : the appearance of a less symmetric tetragonal phase (martensite) in an austenite matrix can mean the appearance of an additional phonon relaxation channel and can result in the determined k ph (T) and η(T) dependences. The coexistence of the austenite and martensite phases near T C in an Ni 50 Mn 35 In 15 alloy also follows from the results in [37].…”

The magnetization, the electrical resistivity, the specific heat, the thermal conductivity, and the thermal diffusion of a polycrystalline Heusler alloy Ni 45.37 Mn 40.91 In 13.72 sample are studied. Anomalies, which are related to the coexistence of martensite and austenite phases and the change in their ratio induced by a magnetic field and temperature, are revealed and interpreted. The behavior of the properties of the alloy near Curie temperature T C also demonstrates signs of a structural transition, which suggests that the detected transition is a first-order magnetostructural phase transition. The nontrivial behavior of specific heat detected near the martensite transformation temperatures is partly related to a change in the electron density of states near the Fermi level. The peculiar peak of phonon thermal conductivity near the martensitic transformation is interpreted as a consequence of the appearance of additional soft phonon modes, which contribute to the specific heat and the thermal conductivity.

“…Consequently, these materials are attractive candidates for multifunctional devices, where magnetic and structural characteristics may be manipulated by applied magnetic fields. Since, the magnetocaloric effect results from magnetization changes, remarkable MCE values and time dependency of adiabatic temperature changes have already been reported for these alloys [1,[5][6][7][8][9][10][11][12][13][14] and, in Ref. [15],…”

The largest measured changes were T ad = -2 K and 2 K near the martensitic (first order) and ferromagnetic (second order, at T C ) transitions for ∆H = 1.8 T, respectively [7,11].…”

The magnetic properties and reversibility of the magnetocaloric effect of Ni 50 Mn 35 In 15 have been studied in the vicinity of the phase transition using magnetization and direct adiabatic temperature change (ΔT ad) measurements in magnetic fields up to 14 T. The magnetostructural phase transitions (MSTs) between a martensitic phase (MP) with low magnetization (paramagnetic or antiferromagnetic) and a nearly ferromagnetic austenitic phase were detected from thermomagnetic curves, M(T,H), at the applied magnetic fields up to 5 T. The MST temperature was found to be nearly independent of magnetic field for H< 5T, and shifted to lower temperature with the further increase of magnetic field to 14 T. A large and nearly reversible inverse magnetocaloric effect (MCE) with T ad ~-11 К for a magnetic field change of ΔH = 14 T was observed in the vicinity of the MST. The irreversibility of T ad was found to be 1 K. A direct T ad of +7 K for ΔH = 14 T was detected at the second order ferromagnetic-paramagnetic phase transition. The obtained results have been discussed in terms of the suppression of antiferromagnetic correlations with the application of a strong magnetic field, and a reversibility of the initial magnetic state of the MP with applied magnetic field when the MST coincides with T C .

“…The bulk sample's indirect measurement shows 14% higher ∆T ad over the direct measurements. This difference is related to the improper use of Maxwell's equations in calculating the MCE of hysteretic materials 41 and heat losses. Also, direct MCE measurement of the nanostructured sample displays 5% less ∆T ad compared to the indirect measurement.…”

“…1 The use of Maxwell equations to describe ∆S M in materials that have a first-order phase transition (FOPT) has been questioned as they are only valid at thermal equilibrium. 41 Nevertheless, it has been recently shown that this artifact can be minimized after using appropriate protocol for the measurements. 42,43 Though, when FOPT occurs, results obtained from Maxwell's equations should be taken with caution.…”

A systematic study of the magnetocaloric effect of a Ni51Mn33.4In15.6 Heusler alloy converted to nanoparticles via high energy ball-milling technique in the temperature range of 270 to 310 K has been performed. The properties of the particles were characterized by x-ray diffraction, electron microscopy, and magnetometer techniques. Isothermal magnetic field variation of magnetization exhibits field hysteresis in bulk Ni51Mn33.4In15.6 alloy across the martensitic transition which significantly lessened in the nanoparticles. The magnetocaloric effects of the bulk and nanoparticle samples were measured both with direct method, through our state of the art direct test bed apparatus with controllability over the applied fields and temperatures, as well as an indirect method through Maxwell and thermodynamic equations. In direct measurements, nanoparticle sample’s critical temperature decreased by 6 K, but its magnetocaloric effect enhanced by 17% over the bulk counterpart. Additionally, when comparing the direct and indirect magnetocaloric curves, the direct method showed 14% less adiabatic temperature change in the bulk and 5% less adiabatic temperature change in the nanostructured sample.
