Magnetic Order and Lattice Instabilities in NiMnSn Heusler based Magnetic Shape-Memory Alloys
Vijay Singh, Ambroise van Roekeghem, S. K. Panda +3
The magnetic correlations in the austenite phase and the consequent martensitic transition in inverse magnetocaloric alloys, NiMnSn, have been a matter of deb…
Thermal resistance of GaN/AlN graded interfaces
Ambroise van Roekeghem, Bjorn Vermeersch, Jesús Carrete +1
Compositionally graded interfaces in power electronic devices eliminate dislocations, but they can also decrease thermal conduction, leading to overheating. We quantify the thermal…
Van Hove singularities, chemical pressure and phonons: an angle-resolved photoemission study of KFeAs and CsFeAs
P. Richard, A. van Roekeghem, X. Shi +6
We report an angle-resolved photoemission spectroscopy (ARPES) study of KFeAs and CsFeAs, revealing the existence of a van Hove singularity affecting the electronic…
Vibrational properties of metastable polymorph structures by machine learning
Fleur Legrain, Ambroise van Roekeghem, Stefano Curtarolo +3
Despite vibrational properties being critical for the ab initio prediction of the finite temperature stability and transport properties of solids, their inclusion in ab initio mate…
