Duality of Wave Modulation and Nanotwinning in Ni-Mn-Ga Martensite via Long-Period Commensurate States
P. VeÅtát, 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…

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…

Compliant Lattice Modulations Enable Anomalous Elasticity in Ni-Mn-Ga Martensite
Kristýna RepÄek, 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…
