Query: Riemannian 2-D conical geometry of Heisenberg ferromagnets   An exact 2-dimensional conical Riemannian defect solution of 3-dimensional
Euclidean Einstein equations of stresses and defects representing a shear-free
Heisenberg ferromagnet is given.The system is equivalent to the Einstein
equations in vacuum.Geodesics of magnetic monopoles around the ferromagnet are
also investigated.
