Electronic structure study by means of X-ray spectroscopy and theoretical calculations of the "ferric star" single molecule magnet
A. F. Takacs, M. Neumann, A. V. Postnikov +5
The electronic structure of the single molecule magnet system M[Fe(L)2]3*4CHCl3 (M=Fe,Cr; L=CH3N(CH2CH2O)2) has been studied using X-ray photoelectron spectroscopy, X-ray absorptio…

Ferromagnetic coupling and magnetic anisotropy in molecular Ni(II) squares
R. Koch, O. Waldmann, P. Mueller +2
We investigated the magnetic properties of two isostructural Ni(II) metal complexes [Ni4Lb8] and [Ni4Lc8]. In each molecule the four Ni(II) centers form almost perfect regular squa…

Butterfly hysteresis loop at non-zero bias field in antiferromagnetic molecular rings: cooling by adiabatic magnetization
O. Waldmann, R. Koch, S. Schromm +3
At low temperatures, the magnetization of the molecular ferric wheel NaFe exhibits a step at a critical field due to a field-induced level-crossing. By means of high-fiel…
