Temperature dependence of magnetic anisotropy and domain wall tuning in BaTiO3(111)/CoFeB multiferroics
Robbie G. Hunt, Kévin J. A. Franke, Paul S. Keatley +3
Artificial multiferroics consist of two types of ferroic materials, typically a ferroelectric and ferromagnet, often coupled interfacially by magnetostriction induced by the lattic…
Dynamics of bistable Néel domain walls under spin-orbit torque
Eloi Haltz, Kévin J. A. Franke, Christopher H. Marrows
Néel magnetic domain walls that are stabilized by achiral energy terms instead of the usual Dzyaloshinskii-Moriya interaction will be bistable, with the two possible chiral forms b…
