Abstract

The molecule-based magnet [Ru2(O2CMe)4]3[Cr(CN)6] contains two interpenetrating sublattices that behave like giant antiferromagnetically coupled moments with strong anisotropy. Because the sublattice moments only weakly depend on field, the volume of magnetically correlated clusters can be directly estimated from the field and temperature dependence of the magnetization while a polycrystalline sample undergoes a metamagnetic transition between antiferromagnetic and paramagnetic states.
