Description

In the present paper we describe the results of Moessbauer measurements on the antiferromagnetic wheel Cr7Fe(II). From the spectra without external field in [1.8,14.8] K range we analyse the spin dynamics vs. T and we evaluate the electric hyperfine parameters. From the 1.8 K spectrum collected in the presence of a 1.5 10-2 T magnetic field, we determine the hyperfine field intensity. The corresponding spin of the iron ion in the complex is estimated and it is found to be in agreement with reported results of original calculations.
