Magnetic Cluster Excitations
Albert Furrer, Oliver Waldmann
Magnetic clusters, i.e., assemblies of a finite number (between two or three and several hundred) of interacting spin centers which are magnetically decoupled from their environmen…
Field-induced level crossings in spin clusters: Thermodynamics and magneto-elastic instability
O. Waldmann
Quantum spin clusters with dominant antiferromagnetic Heisenberg exchange interactions typically exhibit a sequence of field-induced level crossings in the ground state as function…
Magnetic molecular wheels and grids - the need for novel concepts in "zero-dimensional" magnetism
O. Waldmann
Supramolecular chemistry has allowed the production, by self-assembly, of inorganic complexes with a [N x N] square matrix-like configuration of N^2 metal centers. Interest in thes…
Mesoscopic quantum coherence in antiferromagnetic molecular clusters
O. Waldmann, C. Dobe, H. Mutka +2
From inelastic neutron scattering experiments, we demonstrate quantum tunneling of the Neel vector in the antiferromagnetic molecular ferric wheel CsFe8. Analysis of the linewidth…
