Transversal transport of magnons in a modified Lieb lattice
P. G. de Oliveira, A. S. T. Pires
We studied a two-band magnon insulating model whose geometry is that of a modified Lieb lattice in which one of the sites was removed. Anisotropic ferromagnetic exchange interactio…

Vortex core dynamics induced by hole defects in antiferromagnetic nanodisks
R. L. Silva, R. D. Pereira, A. R. Pereira +3
Direct observation of vortex states in an antiferromagnetic layer have been recently reported [Wu, et al, Nature Phys. 7, 303 (2011)]. In contrast to their analogues in ferromagnet…

Spinwave damping in the two-dimensional ferromagnetic XY model
G. M. Wysin, M. E. Gouvea, A. S. T. Pires
The effect of damping of spinwaves in a two-dimensional classical ferromagnetic XY model is considered. The damping rate is calculated using the leading diagrams due to the…
