Magnetic self-frustration from spontaneous structural distortion
T. Vignau Costa, G. L. Rossini, D. C. Cabra +2
In frustrated magnetism, lattice distortions mediated by magnetoelastic coupling are commonly invoked as an escape route from extensive degeneracy toward an ordered ground state an…
Topological transitions in spin-ice induced by geometrical constraints
R. A. Borzi, E. S. Loscar, S. A. Grigera
We study the nearest-neighbor spin-ice model subjected to a magnetic field applied along the global [111] and [110] directions, focusing on the role of sample geometry in stabilizi…
Investigation into the low temperature state of the spin-ice material Dy_2 Ti_2 O_7
Mariano Marziali Bermudez, R. A. Borzi, D. A. Tennant +1
The thermal equilibrium properties of the spin-ice material DTO, including specific heat, magnetization, and spin correlations, could be successfully reproduced by a model featurin…
Dipolar effects on the behavior of magnetically diluted spin-ice
M. Gorsd, S. A. Grigera, R. A. Borzi
In this work, we explore the magnetic behavior of diluted spin-ice systems, where magnetic moments are randomly removed at various concentrations. We concentrate on features in whi…
Perfectly hidden order and Z2 confinement transition in a fully packed monopole liquid
Attila Szabo, Santiago A. Grigera, P. C. W. Holdsworth +5
We investigate a variant of spin ice whose degenerate ground states are densely packed monopole configurations. An applied field drives this model through a Z2 confinement transiti…
Numerical Simulations of the Magnetodielectric response in Ising Pyrochlores
Tomas Vignau Costa, Santiago Grigera, Rodolfo Borzi
In this paper, we examine the magnetoelectric response of Ising pyrochlores, focusing on both the ordered antiferromagnetic state and the frustrated ferromagnetic case known as "sp…
