Solute strengthening of prism edge dislocations in Mg alloys

William Curtin, Masoud Rahbarniazi

The poor ductility of hcp Mg is attributed to the low activity of non-basal slip systems and so activation of prismatic slip can aid ductility in rolled sheets by providing three additional < a > Burgers vector slip systems. Experimental studies show that ...

Weyl spin-momentum locking in a chiral topological semimetal

Jan Hugo Dil, Eduardo Bonini Guedes

Spin-orbit coupling in noncentrosymmetric crystals leads to spin-momentum locking - a directional relationship between an electron's spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin-momentum locking has been studied for decad ...
