Proof of concept for micro pulling down growth of phase change materials in the example system of NiTi — Lauritz Schnatmann, •Timon Sieweke, and Gabi Schierning — University of Bielefeld

The micro pulling down growth method (mPD) is a common approach to synthesize small crystals for material screening in e.g. high-entropy oxides. Another interesting group of materials are phase change materials namely showing unique structural transitions interplaying with electronic and magnetic contributions. However, the interplay between the different contributions is strongly dependent on the composition of materials. We built up a micro pulling down set up for fast material screening of phase changing materials. We grew a NiTi- shape memory alloy to show the possibility of comparable easy growth of crystals by mPD. Hereby, we verified mPD as a powerful tool for the versatile fabrication of small crystals in the field of phase change materials.
