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 {…
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…
Strong Coulomb effects in hole-doped Heisenberg chains
J. Schnack
Substances such as the ``telephone number compound'' Sr14Cu24O41 are intrinsically hole-doped. The involved interplay of spin and charge dynamics is a challenge for theory. In this…
Exact diagonalization studies of doped Heisenberg spin rings
J. Schnack, F. Ouchni
Motivated by magnetization studies of the "telephon number compound" Sr_14Cu_24O_41 we investigate doped Heisenberg spin rings by means of complete numerical diagonalization of a H…
Exchange interactions and magnetic anisotropy in the "Ni_4" magnetic molecule
A. V. Postnikov, M. Brueger, J. Schnack
Magnetic properties of a tetrahedral "Ni_4" molecule are discussed in terms of the Heisenberg model, with magnetic anisotropy terms included, and on the basis of first-principle ca…
Magnetic characterization of the frustrated three-leg ladder compound [(CuCl2tachH)3Cl]Cl2
J. Schnack, Hiroyuki Nojiri, P. Koegerler +2
We report the magnetic features of a new one-dimensional stack of antiferromagnetically coupled equilateral copper(II) triangles. High-field magnetization measurements show that th…
