Reversible tuning of magnetocaloric Ni-Mn-Ga-Co films on ferroelectric PMN-PT substrates
Benjamin Schleicher, Robert Niemann, Stefan Schwabe +4
Tuning functional properties of thin caloric films by mechanical stress is currently of high interest. In particular, a controllable magnetisation or transition temperature is desi…
Modulations in martensitic Heusler alloys originate from nanotwin ordering
Markus E. Gruner, Robert Niemann, Peter Entel +4
Heusler alloys exhibiting magnetic and martensitic transitions enable applications like magnetocaloric refrigeration and actuation based on the magnetic shape memory effect. Their…
Nucleation and growth of hierarchical martensite in epitaxial shape memory films
Robert Niemann, Anja Backen, Sandra Kauffmann-Weiss +7
Shape memory alloys often show a complex hierarchical morphology in the martensitic state. To understand the formation of this twin-within-twins microstructure, we examine epitaxia…
