Systematic trends of transformation temperatures and crystal structure of Ni-Mn-Ga-Fe-Cu alloys
Here we report a systematic research on effects of Fe and Cu upon properties relevant for the magnetic shape memory effect of Ni–Mn–Ga ferromagnetic shape memory alloys. Fe and Cu were identified as elements with potential synergism to increase the m...

Origin of magnetocrystalline anisotropy in Ni-Mn-Ga-Co-Cu tetragonal martensite
We investigate the origin of magnetocrystalline anisotropy (MCA) in non-modulated martensite of Ni-Mn-Ga-Co-Cu exhibiting magnetic-field-induced strain up to 12%. Experiments as well as theoretical calculations using density functional theory show th...

First-principles study of Zn-doping effects on phase stability and magnetic anisotropy of Ni-Mn-Ga alloys
The effect of Zn doping on Ni-Mn-Ga magnetic shape memory alloy was studied by the firstprinciples calculations using exact muffin-tin orbital method in combination with the coherentpotential approximation and projector augmented-wave method. Trends ...

Fe2MnSn Experimental quest for predicted Heusler alloy
Fe2MnSn compound was prepared in the form of polycrystalline ingot by arc-melting. In contrast to the theoretical predictions of stable tetragonal Heusler compound, the material crystallizes in a hexagonal DO19 crystal structure and orders ferromagne...

Magnetic and magneto-optical properties of Fe75-xMn25Gax Heusler-like compounds
Fe-Mn-Ga Heusler-like compounds were analyzed in a wide range of Fe/Ga ratios while keeping the Mn content constant and equal 25at%. Materials were prepared by arc-melting from pure elements and annealed. Experiments focused on magnetization from 4 t...

Ultrafast actuation of Ni-Mn-Ga micropillars by pulsed magnetic field
We report on the pulsed magnetic field actuation of single crystalline Ni-Mn-Ga cuboid micropillars with dimensions of 40 × 45 × 120 μm3, created by focused ion beam milling followed by electrochemical etching. Based on the experimental and modelled ...

Magnetic coercivity control by heat treatment in Heusler Ni-Mn-Ga(-B) single crystals
The combination of enlarged magnetic coercivity and magnetic shape memory (MSM) functionality is essential for novel magnetomechanical effects in MSM alloys. We found that increasing the density of thermal antiphase boundaries (APBs) provides a metho...

Rapid floating zone growth of Ni2MnGa single crystals exhibiting magnetic shape memory functionality
To obtain a material exhibiting magnetically induced reorientation (MIR), one of the magnetic shape memory effects, a well-developed method for single crystal growth is crucial. A ½100 oriented Ni2MnGa single crystal exhibiting MIR was successfully ...
