We find that, in ferromagnetic materials, two types of hopfions, Bloch-type and Néel-type hopfions, can be excited as metastable states in the presence of bulk and interfacial Dzyaloshinskii-Moriya interactions, respectively.
Web31 mrt. 2024 · Magnetic hopfions are stabilized in chiral magnets as a result of antisymmetric exchange interaction, commonly called the Dzyaloshinskii–Moriya interaction (DMI). Depending on the origin of DMI, i.e., bulk or interfacial DMI, Bloch or Neel hopfions are stabilized in magnetic nanodisks.
