A highly stable plating bath for the electrodeposition of Fe-Pd nanowires into nanoporous alumina templates has been developed. Complexing of both metal ions and exchanging Fe2+ by Fe3+ avoid chemical reduction of Pd ions and, therefore, undesirable deposition. By using a pulse potential mode and appropriate adjustment of deposition potentials homogeneously filled templates without surface deposits and nanowires close to the desired composition of Fe70Pd30 have been achieved. These alloy nanowires represent a key step towards nanoactuators based on magnetic shape memory alloys. © 2010 Elsevier B.V. All rights reserved.

Ferromagnetic shape memory alloys, including the Fe7Pd3 system, constitute an upcoming class of functional materials, whose atomic-scale physical foundations are still insufficiently understood. The present work employs molecular dynamics simulations, based on ab initio derived embedded atom method potentials, to study martensitic transformations and twin variant reorientation. We address thermal and stress induced austenite-martensite transitions, twinning, as well as twin boundary mobility. While the predicted thermal properties are in accordance with experimental observations, we explore the detailed crystallography underlying transformation as well as twin boundary motion. © 2019 The Author(s).
