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…
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…
On energetics of allotrope transformations in transition-metal diborides via plane-by-plane shearing
Thomas Leiner, Nikola Koutná, Jozef Janovec +3
Transition metal diborides crystallise in the , , or type structure, in which pure transition metal layers alternate with pure boron layers stacked along the hexagonal [0…
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…
