Binding a hopfion in a chiral magnet nanodisk
Hopfions are three-dimensional (3D) topological textures characterized by the integer Hopf invariant QH. Here we present the realization of a zero-field, stable hopfion spin texture in a magnetic system consisting of a chiral magnet nanodisk sandwiched by two films with perpendicular magnetic anisotropy. The preimages of the spin texture and ...
