## Abstract The off‐stoichiometric Ni~2~MnGa Heusler alloy is a magnetic shape‐memory alloy capable of reversible magnetic‐field‐induced strains (MFIS). These are generated by twin boundaries moving under the influence of an internal stress produced by a magnetic field through the magnetocrystallin

The present work contains a high-resolution transmission electron microscopy study (including image simulations) of the layered martensitic structures formed in Ni-Mn-Ga alloys. The main purpose is to distinguish two structural models proposed in the literature. For the seven-layered martensite, the
Single-crystalline 5M (exhibiting magnetic shape memory effect) and non-modulated martensitic Ni-Mn-Ga alloys were studied by dynamic mechanical analysis (DMA) at different temperatures. The chemical compositions of the alloys were determined using energy-dispersive X-ray spectrometry in a scanning
Partial substitution of Ni by Co in Mn-rich Ni-Mn-Ga alloys has been found to modify the magnetic ordering of the phases, improving in this way the possibility to obtain large magnetization difference between austenite and martensite, an essential requirement to induce the martensitic transformation
The influence of pre-deformation on the martensitic transformation behavior and its microstructure has been put forward in a Ni 55 Mn 20 Ga 25 (at.%) ferromagnetic shape memory alloy. It is found that the reverse martensitic transformation temperatures (A s and A f ) increase linearly with increasin
