Hopfions in chiral magnets.

Sutcliffe, Paul (2018) 'Hopfions in chiral magnets.', Journal of physics A : mathematical and theoretical., 51 (37). p. 375401.

Abstract

A magnetic Hopfion is a three-dimensional topological soliton that consists of a closed loop of a twisted magnetic Skyrmion string. The results of numerical simulations are presented that demonstrate the existence of a stable Hopfion in a nanocylinder of a chiral magnet and an explicit analytic expression is shown to provide a reasonable approximation to the numerically computed Hopfion. A mechanism is suggested to create the Hopfion from a target Skyrmion by introducing an interfacial perpendicular magnetic anisotropy.
