Frustration-induced exotic properties of magnetic molecules
J. Schnack
Geometric frustration of interacting spin systems is the driving force of a variety of fascinating phenomena in low-dimensional magnetism. In this contribution I will review recent…
Frustration effects in magnetic molecules
J. Schnack
Besides being a fascinating class of new materials, magnetic molecules provide the opportunity to study concepts of condensed matter physics in zero dimensions. This contribution w…
Observation of field-dependent magnetic parameters in the magnetic molecule {Ni4Mo12}
J. Schnack, M. Brueger, M. Luban +9
We investigate the bulk magnetic, electron paramagnetic resonance, and magneto-optical properties of {Ni4Mo12}, a magnetic molecule with antiferromagnetically coupled tetrahedral {…
Revisiting the chain magnetism in Sr14Cu24O41: Experimental and numerical results
R. Klingeler, B. Buchner, K. -Y. Choi +4
We study the magnetism of the hole doped CuO2 spin chains in Sr14Cu24O41 by measuring the Electron Spin Resonance (ESR) and the static magnetization M in applied magnetic fields up…
Magnetic excitations in {Mo72Fe30}
V. O. Garlea, S. E. Nagler, J. L. Zarestky +11
We report cold-neutron inelastic neutron scattering measurements on deuterated samples of the giant polyoxomolybdate magnetic molecule {Mo72Fe30}. The 30 s = 5/2 Fe+3 ions occupy t…
Theoretical estimates for proton-NMR spin-lattice relaxation rates of heterometallic spin rings
M. Allalen, J. Schnack
Heterometallic molecular chromium wheels are fascinating new magnetic materials. We reexamine the available experimental susceptibility data on MCr7 wheels in terms of a simple iso…
Quantum Theory of Molecular Magnetism
J. Schnack
The synthesis of molecular magnets has undergone rapid progress in recent years. Each of the identical molecular units can contain as few as two and up to several dozens of paramag…
Metamagnetic phase transition of the antiferromagnetic Heisenberg icosahedron
Christian Schröder, Heinz-Jürgen Schmidt, Jürgen Schnack +1
The observation of hysteresis effects in single molecule magnets like Mn-acetate has initiated ideas of future applications in storage technology. The appearance of a hyster…
Frustration effects in magnetic molecules
R. Schmidt, J. Richter, J. Schnack
By means of exact diagonalization we study the ground-state and the low-temperature physics of the Heisenberg antiferromagnet on the cuboctahedron and the icosidodecahedron. Both a…
