摘要：

A term in the action that is of third order in the derivatives of the rotation matrix is calculated. A direct diagrammatic method in the limit of high magnetic fields is used. it is shown that the action contains the standard Hopf invariant with a coefficient corresponding to fermionic behavior of vortices/skyrmions.
