On the table-like magnetocaloric effect, microstructure and mechanical properties of LaxFe11.6 Si1.4 system

Study on the chemical co-precipitation synthesized CoFe2O4 nanoparticle for magnetocaloric performance in the vicinity of superparamagnetic blocking temperature

“…Numerous sources, including the aforementioned author's work, indicate that increasing the magnetic field strength can enhance our value of maximum entropy change. But Materials like Gd-Si-Ge, La–Fe–Si, Mn–Fe–P-X, and Heusler alloys exhibit substantial magnetocaloric effects (MCE) much better than present CoFe 2 O 4 NPs due to the combined contributions from structural and magnetic entropy changes [ [57] , [58] , [59] , [60] ]. Despite their potential for magnetic refrigeration, these materials often suffer from brittleness and functional fatigue due to volume changes during first-order phase transitions [ 61 ].…”

Magnetocaloric properties of phenolic resin bonded La(Fe,Si)13-based plates and its use in a hybrid magnetic refrigerator

“…Among these magnetocaloric materials, La(Fe,Si) 13 -based compounds are widely accepted as one of the most promising candidates due to their easy and environmentally friendly preparation, low cost, non-toxic constituent elements, and excellent magnetocaloric effect. [21] By partially substituting Fe with Mn [22] or Co, [23] or introducing interstitial hydrogen (H) [24] or carbon (C) [24] in the La(Fe,Si) 13 crystal structure, the Curie temperature T c associated with the optimal operating temperature for a magnetocaloric material can be tuned over a large temperature span from ∼ 170 K to ∼ 340 K, while the large MCE can remain and the hysteresis loss may decrease. The tunable Curie temperature is important for an efficient AMR, as a single material exhibits a large MCE only within a relatively small temperature range near its transition temperature.…”
