“…Because of the high-energy effectiveness and environmental friendliness of magnetic refrigeration (MR) technology, which is established on the basis of the magnetocaloric effect (MCE), has facilitated an alternative to conventional gas refrigeration [1][2][3][4][5]. The MCE is a thermal phenomenon effect associated with magnetic entropy changes (ΔS M ) caused by an external magnetic field change (∆H), particularly at temperatures near to or going to exceed the Curie temperature (T C ) [6][7][8][9][10][11][12][13].…”

The magnetocaloric (MC) effect of α-MnO 2 nanorods is predicted using a phenomenological model. The magnetization vs. temperature simulation results were used to obtain the MC characteristics of α-MnO 2 nanorods. The magnetic entropy change has a full-width at half-maximum of more than 30 K, providing a good solid base for running the α-MnO 2 nanorods in the magnetic refrigerator (MR). Because α-MnO 2 nanorods can be used as an effective MC material for MR at temperatures below 50 K, we conclude that the α-MnO 2 nanorods could indeed act as a desirable MC magnet inside the MR for space applications, hydrogen liquefaction, and cryocoolers based on the current state of results.

The magnetic refrigerator (MR) has gained popularity due to its potential to improve the energy efficiency of refrigeration without the use of unsafe gas, as is the case with traditional gas compression techniques. Magnetocaloric lanthanum manganite investigation, particularly at room and cryogenic temperatures, shows favorable results for the development of MR. Previous thermodynamic models require a significant amount of time and effort to estimate the magnetocaloric effect (MCE). Consequently, we employ the phenomenological model (PM), which is simple and straightforward, requiring fewer parameters than many other modeling methods. We studied the magnetocaloric effect (MCE) of silica-coated La0.54Sr0.27Gd0.19MnO3 (LSGMO) nanoparticles via PM. According to PM results, MCE parameters were obtained as the consequences of the simulated magnetization of silica-coated LSGMO nanoparticles vs. temperature under 0.1 T a magnetic field. It is revealed that the MCE of silica-coated LSGMO nanoparticles covers a broad range of temperatures between 200 and 330 K. The comparison of MCE parameters for silica-coated LSGMO nanoparticles and some published works shows that silica-coated LSGMO nanoparticles are considerably larger than some of the MCE parameters in these published works. Finally, silica-coated LSGMO nanoparticles are suitable function materials in MR, especially at room and cryogenic temperatures, contributing to efficient MR.

The magnetocaloric effect-(MCE) of MgB2 is simulated, considering the effect of sintering temperature on MCE. The results show that MCE of MgB2 samples is an inverse type in a temperature range of diamagnetic-paramagnetic transition. Moreover, the MCE for MgB2 is improved with high sintering temperature. The comparison between MCE of MgB2 samples and other some reported magnetic materials has been done, showing that MCE parameters of MgB2 samples are larger than some MCE parameters of La1-xCdxMnO3, La1.25Sr0.75MnCoO6, Gd1−xCaxBaCo2O5.5, Ni58Fe26Ga28, Ni2+xMn1−xGe, Ge0.95Mn0.05 film, and (001)-oriented MnAs film. It suggested that MgB2 samples could be a promising sharing candidate for MR in cryogenic temperatures.
