Electric Resistivity and Hall Effect of Ni(Co)-Mn-Al Melt Spun Ribbons
Abstract
<jats:p>In the present work the influence of Co alloying on transport properties of Ni-Mn-Al melt-spun ribbons was investigated. Results of electrical resistivity measurements showed that Ni<jats:sub>50</jats:sub>Mn<jats:sub>31</jats:sub>Al<jats:sub>19</jats:sub> and Ni<jats:sub>45</jats:sub>Co<jats:sub>5</jats:sub>Mn<jats:sub>32</jats:sub>Al<jats:sub>18</jats:sub> samples exhibit a temperature hysteresis of the electrical resistivity which was attributed to a first order martensitic transformation while no hysteresis was observed in Ni<jats:sub>40</jats:sub>Co<jats:sub>10</jats:sub>Mn<jats:sub>33</jats:sub>Al<jats:sub>17</jats:sub> sample. Measurements of the Hall effect indicated that the Co alloying leads to an increase of carrier mobility.</jats:p>
