Magnetostructural transition and magnetocaloric effect in Mn<sub>0.5</sub>Fe<sub>0.5</sub>NiSi<sub>1−x</sub>Al<sub>x</sub> melt-spun ribbons (<i>x</i> = 0.055 and 0.060)
Abstract
<jats:p> Melt-spun ribbons samples of the multicomponent alloy Mn<jats:sub>0.5</jats:sub>Fe<jats:sub>0.5</jats:sub>NiSi<jats:sub>0.940</jats:sub>Al<jats:sub>0.060</jats:sub> were prepared and the magnetostructural transition (MST) and related magnetocaloric properties studied for as-solidified ribbons and ribbon samples annealed between 800 and 950 °C for 4 h. The results are compared with those reported in the literature for melt-spun ribbons with an Al content x = 0.055 and bulk alloys. It is shown that all samples undergo a first-order MST from a paramagnetic Ni<jats:sub>2</jats:sub>In-type hexagonal structure to a ferromagnetic TiNiSi-type orthorhombic one. Ribbons show broader isothermal entropy change Δ S<jats:sub>T</jats:sub>( T) curves with moderate maximum values of |Δ S<jats:sub>T</jats:sub>|<jats:sup>max</jats:sup> at 2 T (7.2–7.3 J kg<jats:sup>−1</jats:sup> K<jats:sup>−1</jats:sup>) in comparison with the reported for bulk alloys. However, the average value of the magnetic hysteresis loss linked to the hexagonal-to-orthorhombic transition is low in comparison with the one reported for most magnetocaloric materials with first-order magnetostructural transitions. This work underlines the effectiveness of this rapid solidification technique to produce highly homogeneous ribbon samples of multicomponent alloys. </jats:p>
