Abstract
Magnetisation in the Pd2MnSn Heusler alloy was observed to be drastically reduced by plastic deformation. The reduction is able to be explained in terms of the dislocation theory with the consideration of ferromagnetic and antiferromagnetic Mn-Mn interactions. Plastic deformation makes Mn atoms on the regular site substitute to Sn and Pd sites. The number of these Mn atoms is proportional to the dislocation density, rho , or its square root, and is estimated to be 1020 cm-3, when rho =1012 cm-2, which is in good agreement with the experimental results.Keywords
