Magnetic shape memory materials require a high twin boundary mobility and low hysteresis
for applications mainly as actuators, sensors, and magnetocaloric cooling elements. Usually …

The straining of non-modulated (NM) Ni–Mn–Ga martensite was studied by in situ
transmission electron microscopy (TEM). Initially, the self-accommodated NM martensitic …

Modulated martensites play an important role in magnetic shape memory alloys, because all
functional properties are closely connected to the twin microstructure and the phase …

We use X-ray diffraction to confirm that the 5M phase of the stoichiometric Heusler alloy Ni 2
MnGa has an incommensurate modulation with wavevector q=[0.428 0.428 0]. We find the …

In order to explain the formation of low-temperature phases in stoichiometric Ni2MnGa
magnetic shape memory alloy, we investigate the phase transformation paths from cubic …

We have found low temperature a/b nanotwins having (110) twinning plane in a five-layered
modulated martensite phase of Ni50Mn25+ x Ga25− x (at.%) Heusler alloys and identified …

Reviewing the results of recent first‐principles calculations, we work out a close analogy
between the two paradigmatic classes of magnetic shape memory materials, the ordered …

The temperature evolution of the structure of Ni 50.0 Mn 28.7 Ga 21.3 single crystals
exhibiting magnetic shape memory effect was investigated near the martensitic …

Using common and high resolution transmission electron microscopy (TEM), we study the
magnetic and crystal phase structures as well as their evolution in Ni 50 Mn 25 Ga 20 Fe 5 …

The flat-cone diffractometer E2 at the research reactor BER II is a thermal neutron single-
crystal diffractometer for 3D reciprocal space map** by using four delay-line area …
