Mössbauer studies on the Fe(II) oxalate spin ladder Na2Fe2(C2O4)(3)(H2O)(2)
Mössbauer studies on the Fe(II) oxalate spin ladder Na2Fe2(C2O4)(3)(H2O)(2)
We investigated the magnetic correlations in the Fe spin ladder system Na2Fe2(C2O4)(3)(H2O)(2) by magnetic susceptibility and Fe-57 Mossbauer spectroscopy between 2 and 310 K. The susceptibility exhibits a broad maximum at about 20 K indicating antiferromagnetic coupling and a S = 0 dimer formation. The Mossbauer measurements reveal a temperature dependent quadrupole splitting and a non-magnetic ground state. The orbital ground state is identified as a singlet with an excited doublet at 383 K in the T-2g manifold.

Abstract
We investigated the magnetic correlations in the Fe spin ladder system Na2Fe2(C2O4)(3)(H2O)(2) by magnetic susceptibility and Fe-57 Mossbauer spectroscopy between 2 and 310 K. The susceptibility exhibits a broad maximum at about 20 K indicating antiferromagnetic coupling and a S = 0 dimer formation. The Mossbauer measurements reveal a temperature dependent quadrupole splitting and a non-magnetic ground state. The orbital ground state is identified as a singlet with an excited doublet at 383 K in the T-2g manifold.
