Geometrical pinning of magnetic vortices induced by a deficit angle on a surface: anisotropic spins on a conic space background
W. A. Moura-Melo, A. R. Pereira, L. A. S. Mol +1
We study magnetic vortex-like excitations lying on a conic space background. Two types of them are obtained. Their energies appear to be linearly dependent on the conical aperture…

Extinction of BKT transition by nonmagnetic disorder in planar-symmetry spin models
G. M. Wysin, A. R. Pereira, I. A. Marques +2
The Berezinskii-Kosterlitz-Thouless (BKT) transition in two-dimensional planar rotator and XY models on a square lattice, diluted by randomly placed vacancies, is studied here usin…
