Modulations in martensitic Heusler alloys originate from nanotwin ordering
Markus E. Gruner, Robert Niemann, Peter Entel +4
Heusler alloys exhibiting magnetic and martensitic transitions enable applications like magnetocaloric refrigeration and actuation based on the magnetic shape memory effect. Their…
On the rich magnetic phase diagram of (Ni, Co)-Mn-Sn Heusler alloys
Anna Grünebohm, Heike C. Herper, Peter Entel
We put a spotlight on the exceptional magnetic properties of the metamagnetic Heusler alloy (Ni,Co)-Mn-Sn by means of first principles simulations. In the energy landscape we find…
Mastering hysteresis in magnetocaloric materials
Oliver Gutfleisch, Tino Gottschall, Maximilian Fries +8
Hysteresis is more than just an interesting oddity, which occurs in materials with a first-order transition. It is a real obstacle on the path from existing lab-scale prototypes of…
Ab initio study of the interface properties of Fe/GaAs(110)
A. Grünebohm, H. C. Herper, P. Entel
We have investigated the initial growth of Fe on GaAs(110) by means of density functional theory. In contrast to the conventionally used (001)-surface the (110)-surface does not re…
A critical discussion of calculated modulated structures, Fermi surface nesting and phonon softening in magnetic shape memory alloys NiMn(Ga, Ge, Al) and CoMn(Ga, Ge)
A. T. Zayak, P. Entel
A series of first principles calculations have been carried out in order to discuss electronic structure, phonon dynamics, structural instabilities and the nature of martensitic tr…
A First-Principles Investigation of Phonon Softenings and Lattice Instabilities in the Shape-Memory System NiMnGa
A. T. Zayak, P. Entel, J. Enkovaara +2
Ferromagnetic \nmg has unique magnetoelastic properties. These are investigated by detailed computational studies of the phonon dispersion curves for the non-modulated cubic \Ltw a…
