The effect of grain boundaries on magnetic exchange interactions in iron
Martin Zelený, Martin Heczko, Petr Šesták +3
This work investigates how grain boundaries (GBs) modify magnetic exchange interactions in bcc iron, with particular focus on the effect of phosphorus segregation. Using density-fu…

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…
