On topological spin excitations on a rigid torus
V. L. Carvalho-Santos, A. R. Moura, W. A. Moura-Melo +1
We study Heisenberg model of classical spins lying on the toroidal support, whose internal and external radii are and , respectively. The isotropic regime is characterized b…

Magnetic monopole and string excitations in a two-dimensional spin ice
L. A. S. Mol, R. L. Silva, R. C. Silva +3
We study the magnetic excitations of a square lattice spin-ice recently produced in an artificial form, as an array of nanoscale magnets. Our analysis, based upon the dipolar inter…
