SUMMARY:Vincent BALTZ : Altermagnetism
DESCRIPTION:\nRésumé : Altermagnets are characterized by anisotropic and asymmetric spin densities across their magnetic sublattices (Figure) and are described by a multipolar order parameter, sharing conceptual similarities with frameworks developed for superconductors and multiferroics [1,2]. This anisotropy is rooted in crystal symmetry, whether intrinsic or engineered through growth, and gives rise to a range of distinctive physical properties. In particular, altermagnets combine the best of both worlds: the spin-polarized currents of ferromagnets with the ultrafast dynamics and zero net magnetization of antiferromagnets. As such, they offer promising opportunities for the next generation of spintronic devices. In this presentation, I will showcase this emerging class of materials, with particular emphasis on our workhorse light-element altermagnet Mn5Si3\n\n\n\nRéférences:\n\n\n\n[1] C Song et al, Altermagnets as a new class of functional materials, Nat.
