NaV 3 (OH) 6 (SO 4 ) 2 : A Kagomé-Type Vanadium(III) Compound with Strong Intralayer Ferromagnetic Interactions

A dominant ferromagnetic exchange interaction propagates about the magnetic sites of the Kagomé lattice of the title compound through the bridging hydroxy groups (see section of the structure). This is at variance with the antiferromagnetic exchange observed for jarosite and its derivatives. The fer...

Zusammenfassung:A dominant ferromagnetic exchange interaction propagates about the magnetic sites of the Kagomé lattice of the title compound through the bridging hydroxy groups (see section of the structure). This is at variance with the antiferromagnetic exchange observed for jarosite and its derivatives. The ferromagnetism probably arises from the d electron count of the V centers.
