This review of the current state of magnetocalorics is focused on materials exhibiting a giant magnetocaloric response near room temperature. To be economically viable for industrial applications and mass production, materials should have desired useful properties at a reasonable cost and should be safe for humans and the environment during manufacturing, handling, operational use, and after disposal. The discovery of novel materials is followed by a gradual improvement of properties by compositional adjustment and thermal or mechanical treatment. Consequently, with time, good materials become inferior to the best. There are several known classes of inexpensive materials with a giant magnetocaloric effect, and the search continues.

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.

“…These types of transitions are commonly observed in alloys containing lanthanide elements (rare earths), due to their electronic configuration [13,14]. Alloys based on these elements have the best magnetocaloric response; however, these materials are very expensive, due to their obtaining and processing methods.The use of 3d transition elements has also attracted considerable attention, due to their unique physical properties and promising applications, such as magnetic field-induced shape memory effect, magnetic field-induced strain, magnetocaloric effect, and magnetoresistance [15][16][17][18]. The magnetocaloric effect in Ni-Mn and Ni-Mn-Z (Z = Ni, Cu, Co, Fe, Mn, and Cr) Heusler alloys leads to an existing field, which is considerably less expensive and higher effective than conventional rare-earth-based magnetocaloric alloys [15].…”

It has been found that the magnetic properties and phase stability of these systems are sensitive to small changes in the concentrations of the parent components and the substitution of Ni, Mn, or In by an additional element Z [15][16][17][18]. The phenomena related to the magneto-structural transitions are highly dependent on the weighted average radius of the constituent ions [16].…”

Effect of Quenching and Normalizing on the Microstructure and Magnetocaloric Effect of a Cu–11Al–9Zn Alloy with 6.5 wt % Ni–2.5 wt % Fe

et al. 2019

View full text Add to dashboard Cite

First-order phase transitions (FOPT) and second-order phase transitions (SOPT) are commonly observed in Cu alloys containing lanthanide elements, due to their electronic configuration, and have an important effect on the optimization of their magnetocaloric effect (MCE). Alloys containing rare earths have the best magnetocaloric response; however, these elements are very expensive, due to their obtaining and processing methods. The present work reports the effect of using 3d transition elements and thermal treatments on the microstructure and MCE of Cu-11Al-9Zn alloys with 6.5 wt % Ni and 2.5 wt % Fe. It was found that thermal treatments of quenching and normalizing, as well as the use of Ni and Fe, have an important influence on both the resulting phases and MCE of the investigated alloy. MCE was calculated indirectly from the change in the magnetic entropy (-∆S m ) under isothermal conditions, using Maxwell´s relation; it was found that samples subjected to normalizing presented a higher magnetocaloric effect than samples with quenching, which was related to the greater disorder in the alloy, due to the coexistence of β 1 + β phases. Magnetochemistry 2019, 5, 48 2 of 12The entropy of such a system can be considered as the sum of two contributions: the entropy related to magnetic ordering and the entropy related to the temperature of the system. Application of a magnetic field will order the magnetic moments comprising the system, which are disordered by the thermal agitation energy, and consequently, the entropy depending on the magnetic ordering (the magnetic entropy, S m ) will be lowered. If a magnetic field is applied under adiabatic conditions, when any heat exchange with the surroundings is absent, then the entropy related to the temperature should increase in order to maintain constant the total entropy of the system constant. Increasing this entropy implies that the system heats up and increases its temperature [5].Unlike conventional refrigeration, magnetic refrigeration (MR) does not use gases that can contribute to the global heating and the deterioration of the ozone layer. However, so far only a few prototype refrigeration machines have been presented worldwide, and there are still many scientific and technological challenges to overcome [6,7]. While in conventional refrigeration a fluid undergoes compression/evaporation processes, causing a change in the temperature of the system, MR is based on a magnetization/demagnetization process. Therefore, the efficiency of the equipment used in MR depends strongly on the magnetic behavior of the solid refrigerant [8,9]. MCE can be obtained by promoting first-order transitions (for example, the martensitic transformation) due to a high crystal lattice disorder, which results in an increase of the total system entropy that leads to better cooling capacity [9]. When the material exhibits a ferromagnetic-paramagnetic transition (second-order transition) during service, the refrigeration capacity can be also improved, since the disorder of the system increases ...
