Electrical conductivity and magnetic susceptibility of rutile type CrVNbO/sub 6/, FeVNbO/sub 6/ and NiV/sub 2/Nb/sub 2/O/sub 10/
Electric conductivity (77-300K) and magnetic susceptibility (4.2-300K) of rutile type polycrystalline samples of CrVNbO/sub 6/, FeVNbO/sub 6/ and NiV/sub 2/Nb/sub 2/O/sub 10/ are reported. All three compounds are n-type semiconductors with room-temperature resistivities of the order of 10/sup 2/-10/sup 3/ ohm-cm. CrVNbO/sub 6/ shows ferromagnetic coupling in the high-temperature region and orders antiferromagnetically below 10K. FeVNbO/sub 6/ transforms to a spin glass state below 20K. NiV/sub 2/Nb/sub 2/O/sub 10/ shows evidence of weak antiferromagnetic interactions. The transport properties of the compounds are discussed in terms of structural properties and unpaired d electrons present on the respective transition metal ions.
