Impact of W doping on Fe-rich (Mn,Fe)₂(P,Si) based giant magnetocaloric materials

The influence of doping with the 5d transition metal W has been studied in the quaternary (Mn,Fe)₂(P,Si) based giant magnetocaloric compounds, which is one of the most promising systems for magnetic refrigeration. It is found that W substitution can separately decrease the Curie temperature T_C and retain the thermal...

Tuning Giant Magnetocaloric Materials: A Study of (Mn,Fe)2(P,Si) and NiCoMnTi Heusler Compounds

Solid‐state caloric effects as intrinsic responses from different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐ and electronic‐ fields) have been evaluated near magnetic phase transformations. In the last decades the magnetically driven caloric changes in various magnetocaloric materials (MCMs) have been exploited extensively...

Lithiation of the Fe₂P-based magnetocaloric materials: A first-principles study

The physical properties of the extensively studied Fe₂P material family, well-known for its promising magnetocaloric qualities are greatly influenced by the unit-cell parameters of this hexagonal system. This sensitivity of the various magnetocaloric properties to structural parameters is particularly important for developing a...

Tuneable giant magnetocaloric effect in (Mn,Fe)₂(P,Si) materials by Co-B and Ni-B co-doping

The influence of Co (Ni) and B co-doping on the structural, magnetic and magnetocaloric properties of (Mn,Fe)₂(P,Si) compounds is investigated by X-ray diffraction (XRD), differential scanning calorimetry, magnetic and direct temperature change measurements. It is found that Co (Ni) and B co-doping is an effective approach to tune...
