Building hierarchical martensite
Stefan Schwabe, Robert Niemann, Anja Backen +7
Martensitic materials show a complex, hierarchical microstructure containing structural domains separated by various types of twin boundaries. Several concepts exist to describe th…
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…
Mesoscopic twin boundaries in epitaxial Ni-Mn-Ga films
Anja Backen, Sandra Kauffmann-Weiss, Christian Behler +6
Twin boundaries play an essential role in the use of magnetic shape memory alloy Ni-Mn-Ga as active material. Only if twin boundaries can be moved by an external magnetic field, hi…
Magnetic domain pattern in hierarchically twinned epitaxial Ni-Mn-Ga films
Anett Diestel, Volker Neu, Anja Backen +2
Magnetic shape memory alloys exhibit a hierarchically twinned microstructure, which has been well examined in epitaxial Ni-Mn-Ga films. Here we analyze consequences of this twin wi…
Magnetic domain structure of epitaxial Ni-Mn-Ga films
Anett Diestel, Anja Backen, Volker Neu +2
For the magnetic shape memory effect, knowledge about the interaction between martensitic and magnetic domain structure is essential. In the case of Ni-Mn-Ga bulk material and foil…
Magnetic nanostructures by adaptive twinning in strained epitaxial films
Sandra Kauffmann-Weiss, Markus E. Gruner, Anja Backen +3
We exploit the intrinsic structural instability of the Fe70Pd30 magnetic shape memory alloy to obtain functional epitaxial films exhibiting a self-organized nanostructure. We demon…
