Mn-deficient Ni-Mn-Ga alloys: phase transitions, magnetic properties, and disappearance of martensitic transformation
Valentina Moskvina, Jaroslav Čapek, Michal Rameš +5
Composition gradients formed during directional solidification are generally considered undesirable in Ni-Mn-Ga magnetic shape-memory alloys. However, these gradients offer a highl…
First-principles study of doping influence on twin formation in Ni-Mn-Ga nonmodulated martensite
Petr Šesták, Martin Heczko, Ladislav Straka +2
We investigate how chemical substitution reshapes the energetics of twin formation in non-modulated (NM) Ni-Mn-Ga martensite. Using density functional theory, we compute generalize…
Atomic Topology and Magnetic Microstructure of Highly Mobile Type I and Supermobile Type II Twin Boundaries in 10M Ni-Mn-Ga Single Crystal
Ladislav Straka, Marek Vronka, Jan Maňák +3
The atomic topology and magnetic microstructure of individual, highly mobile Type I and Type II twin boundaries in 10M Ni-Mn-Ga martensite were investigated by transmission electro…
Duality of Wave Modulation and Nanotwinning in Ni-Mn-Ga Martensite via Long-Period Commensurate States
P. Veřtát, M. Zelený, A. Sozinov +8
Structural modulation is a key ingredient behind the extraordinary (magneto)elastic response of Ni-Mn-Ga martensite, yet its link to fine microstructural features and twin-boundary…
Compliant Lattice Modulations Enable Anomalous Elasticity in Ni-Mn-Ga Martensite
Kristýna Repček, Pavla Stoklasová, Tomáš Grabec +8
High mobility of twin boundaries in modulated martensites of Ni-Mn-Ga-based ferromagnetic shape memory alloys holds a promise for unique magnetomechanical applications. This featur…
Ab initio prediction of stable nanotwin double layers and 4O structure in NiMnGa
Martin Zelený, Ladislav Straka, Alexei Sozinov +1
The ab initio electronic structure calculations of the NiMnGa The alloy indicate that the orthorhombic 4O structure exhibits the lowest energy compared to all known martensit…
Thermally induced changes of structure in NiMnGa magnetic shape memory single crystals with very low twinning stress
Ladislav Straka, Jan Drahokoupil, Oliva Pacherová +4
In search for the origins of the extraordinary low twinning stress of Ni-Mn-Ga magnetic shape memory alloys we studied the thermally induced changes of structure in NiMn$_{2…
