E-band excitations in the magnetic Keplerate molecule Fe30
O. Waldmann
The low-temperature excitations in the magnetic Keplerate molecule Fe30 as calculated by linear spin-wave theory (SWT), modified linear SWT, and spin-level mean-field theory (SLMFT…
Quantum dynamics of the Neel vector in the antiferromagnetic molecular wheel CsFe8
O. Waldmann, C. Dobe, H. U. Güdel +1
The inelastic neutron scattering (INS) spectrum is studied for the antiferromagnetic molecular wheel CsFe8, in the temperature range 2 - 60 K, and for transfer energies up 3.6 meV.…
An iron(III) phosphonate cluster containing a nonanuclear ring
H. C. Yao, J. J. Wang, Y. S. Ma +7
This communication reports the first example of cyclic ferric clusters with an odd number of iron atoms capped by phosphonate ligands, namely, [Fe9(m-OH)7(m-O)2(O3PC6H9)8-(py)12].…
Supramolecular Co(II)-[2 x 2] grids: Metamagnetic behavior in a single molecule
O. Waldmann, M. Ruben, U. Ziener +2
The magnetic anisotropy of the supramolecular [2 x 2] grid [Co(II)4L4]8+, with a bis(bipyridyl)-pyrimidine based ligand L, was investigated by single-crystal magnetization measurem…
The mixed-valent manganese [3 x 3] grid [Mn(III)4Mn(II)5(2poap-2H)6](ClO4)10.10H2O, a mesoscopic spin-1/2 cluster
O. Waldmann, H. U. Güdel, T. L. Kelly +1
The magnetic susceptibility, and low-temperature magnetization curve, of the [3 x 3] grid [Mn(III)4Mn(II)5(2poap-2H)6](ClO4)10.10H2O is analyzed within a spin Hamiltonian approach.…
Pressure dependence of the exchange interaction in the dimeric single-molecule magnet [Mn4O3Cl4(O2CEt)3(py)3]2 from inelastic neutron scattering
A. Sieber, D. Foguet-Albiol, O. Waldmann +8
The low-lying magnetic excitations in the dimer of single-molecule magnets (Mn4)2 are studied by inelastic neutron scattering as a function of hydrostatic pressure. The anisotropy…
