We report on various approaches to control the antiferro-ferromagnetic transition temperature of Mn1.2Co0.8Si0.2P0.8 and related materials for magnetocaloric applications. The effects of the Si substitution, Mn/Co ratio and B addition/substitution on MnCoP have been characterized ...

The field dependence of the magnetocaloric effect (MCE) in Mn1.22Fe0.73P0.47Si0.53 is studied in terms of the entropy change (Δ S) and the temperature change (Δ T) for applied magnetic fields up to 5 and 14 T, respectively. The magne ...

An unconventional phenomena is observed at the first-order magnetic transitions in (Mn,Fe)2(P,Si) materials. Here, we show that the first crossing of the transition upon cooling is associated with an abnormal temperature increase. While differential scanning calorimetry can detec ...

We study the spin Hall magnetoresistance effect in ferrimagnet/normal metal bilayers, comparing the response in collinear and canted magnetic phases. In the collinear magnetic phase, in which the sublattice magnetic moments are all aligned along the same axis, we observe the c ...

Magnetic cooling is a highly efficient refrigeration technique with the potential to replace the traditional vapor compression cycle. It is based on the magnetocaloric effect, which is associated with the temperature change of a material when placed in a magnetic field. We presen ...
Recently, materials undergoing a first-order magnetic transition (FOMT) near room temperature have attracted much attentions due to the possibility to use their large magnetocaloric effect (MCE) for magnetic refrigeration [1]. Among them, the MnFe(P, X) (X = As, Ge, Si, B) family ...
