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…
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…
Large Magnetic-Field-Induced Strains in Ni-Mn-Ga Alloys due to Redistribution of Martensite Variants
K. Ullakko, A. Sozinov, P. Yakovenko
A polycrystalline and single-crystal samples of near-stoichiometric Ni2MnGa alloys have been investigated. It was confirmed that martensite short crystallographic axis (c-axis) is…
