Determination of the universality class of Gadolinium
E. Frey, F. Schwabl, S. Henneberger +4
We resolve a longstanding puzzle for the static and dynamic critical behavior of Gadolinium by a combined theoretical and experimental investigation. It is shown that the spin dyna…

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…
