Tuning the metamagnetic transition in the (Co, Fe)MnP system for magnetocaloric purposes

The inverse magnetocaloric effect taking place at the antiferro-to-ferromagnetic transition of (Co,Fe)MnP phosphides has been characterised by magnetic and direct ?Tad measurements. In Co0.53Fe0.47MnP, entropy change of 1.5?Jkg?1?K?1 and adiabatic temperature change of 0.6?K are found at room temperature for an intermediate field change (?B?=?1...

Tunable thermal hysteresis in MnFe(P,Ge) compounds

Structural, magnetic, and magnetocaloric properties of the MnFe(P,Ge) compounds were systematically studied on both bulk alloys and melt-spun ribbons. The experimental results show that the critical behavior of the phase transition can be controlled by changing either the compositions or the annealing conditions. The thermal hysteresis is found...
