We report on the sharpness of the magnetostructural transition in a Ni-Co-Mn-Ga-In Heusler alloy, which has a key role in defining the magnetocaloric effect exploitable in efficient and environmentally friendly magnetic refrigerators. Magnetic and ca

We report on a study on a representative set of FeP-based MnFePSi samples by means of Mn NMR in both zero and applied magnetic field. The first-order nature of the magnetic transition is demonstrated by truncated order parameter curves with a large v

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

In Ni-Mn-Ga ferromagnetic shape memory alloys, Co-doping plays a major role in determining a peculiar phase diagram where, besides a change in the critical temperatures, a change of number, order and nature of phase transitions (e. g., from ferromagn

The addition of boron in MnFe(P,Si) materials has been studied by considering two possibilities: an interstitial intercalation or a substitutional approach. A cell volume decrease with “extra” B addition is observed which is incompatible with an

In this contribution we have analyzed the Heusler class of materials looking for systems presenting large ground-state moments, which can be stabilized into a fully austenite state with a second-order phase transition around room temperature. We have

We compare the magnetocaloric effect of samples prepared with different thermal conductivities to investigate the potential of composite materials. By applying the magnetic field under operating conditions we test the material's response and compare

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,
