Magnetic field-induced degenerate ground state in the classical antiferromagnetic XX model on the icosahedron
N. P. Konstantinidis
The ground state of the classical antiferromagnetic XX model in a magnetic field is calculated for spins mounted on the vertices of the icosahedron. The magnetization is characteri…

Local variations of the magnetization effected by an external field in molecular rings
N. P. Konstantinidis
It is shown that an external magnetic field generates local variations of the classical ground-state magnetization in molecular rings of antiferromagnetic icosahedra with isotropic…

Origin of the classical magnetization discontinuities of the dodecahedron
N. P. Konstantinidis
The classical antiferromagnetic Heisenberg model on the dodecahedron has been shown to have three magnetization discontinuities in an external field. Here it is shown that the high…
