Phase diagram and magnons in quasi-one-dimensional dipolar antiferromagnets
M. Hummel, C. Pich, F. Schwabl
We investigate antiferromagnetic spin chains, which are coupled by a weak antiferromagnetic exchange interaction on a hexagonal lattice. We particulary study the role of the dipole…

Spin waves and phase diagram of one-dimensional, dipolar antiferromagnets
M. Hummel, C. Pich, F. Schwabl
We report on the properties of a dipolar, antiferromagnetic chain in the framework of linear spin-wave theory. The phase diagram is calculated for an arbitrary ratio of dipolar int…
