Structure magnétique et dépendance en champ de la cycloïde incommensurable médiatrice de la transition de réorientation de spins dans Ca3Ru2O7

Quentin FAURE – Université Paris-Saclay, CNRS, CEA, Laboratoire Léon Brillouin Les matériaux présentant un fort couplage spin-orbite ont récemment attiré beaucoup d’attention de par leur potentielle réalisation de nouvelles phases électroniques et magnétiques [1]. Les composés à base de métaux de transition 4d tel que le ruthénium jouent un rôle particulièrement important dans ce domaine, […]

A WAAM benchmark: from process parameters to thermal effects on weld pool shape, microstructure and residual stresses.

Camille Cambon, Issam Bendaoud, Sébastien Rouquette and Fabien Soulié LMGC, Univ. Montpellier, CNRS, Montpellier, France See the full published paper. Wire + arc additive manufacturing (WAAM) process is based on layer-by-layer deposition of melted filler-wire. WAAM is a sort of 3D printer for making metallic parts. The WAAM process, under consideration in this work, uses […]
