Entropic selection of magnetization in a frustrated 2D magnetic model
Anuradha Jagannathan, Thierry Jolicoeur
We discuss the magnetic ground state and properties of a frustrated two-dimensional classical Heisenberg model of interacting hexagonal clusters of spins. The energy of the ground…
Weakening of antiferromagnetism due to frustration on inhomogeneous 2D lattices
A. Jagannathan
This paper discusses the ground state of quantum spins interacting via Heisenberg antiferromagnetic exchange, in two dimensional lattices having several different local environment…
Novel Properties of Frustrated Low Dimensional Magnets with Pentagonal Symmetry
A. Jagannathan, B. Motz, E. Vedmedenko
In the context of magnetism, frustration arises when a group of spins cannot find a configuration that minimizes all of their pairwise interactions simultaneously. We consider the…
Density of states and magnetic susceptibilities on the octagonal tiling
A. Jagannathan
We study electronic properties as a function of the six types of local environments found in the octagonal tiling. The density of states has six characteristic forms, although the…
