Optimized implementation of the Lanczos method for magnetic systems
J. Schnack, P. Hage, H. -J. Schmidt
Numerically exact investigations of interacting spin systems provide a major tool for an understanding of their magnetic properties. For medium size systems the approximate Lanczos…

Competing Spin Phases in Geometrically Frustrated Magnetic Molecules
C. Schroeder, H. Nojiri, J. Schnack +3
We have found a class of zero-dimensional geometrically frustrated Heisenberg spin systems exhibiting anomalous behavior in an external magnetic field B similar to that occuring in…

Quantum numbers for relative ground states of antiferromagnetic Heisenberg spin rings
K. Baerwinkel, P. Hage, H. -J. Schmidt +1
We suggest a general rule for the shift quantum numbers k of the relative ground states of antiferromagnetic Heisenberg spin rings. This rule generalizes well-known results of Mars…
