At low temperatures, some lattice spin models with simple ferromagnetic or antiferromagnetic interactions (for example, nearest-neighbor interaction being isotropic in spin space on a bipartite three-dimensional lattice) produce orientationally ordered phases exhibiting nematic (second-rank) order, in addition to the primary first-rank one; on the other hand, in the literature, they have been rather seldom investigated in this respect. Here we study the thermodynamic properties of a three…

Continuous ground-state degeneracy of classical dipoles on regular lattices

Dipolar interactions are crucial in the modeling of many complex magnetic systems, such as the pyrochlores and artificial spin systems. Remarkably, many classical dipolar coupled spin systems exhibit

Nematic order in a simple-cubic lattice-spin model with full-ranged dipolar interactions.

This work addresses the full-ranged counterpart of the three-dimensional simple-cubic lattice model with dipolarlike interaction, for which the existence of an ordering transition at finite temperature had been proven mathematically; here, there were recognizable quantitative differences between the two models.
