| الوصف: | We have investigated the magnetic and electrical resistance behaviour of Ca3−xYxLiRuO6. The parent compound exhibits magnetic ordering from Ru sublattice at a rather high temperature, 113 K. Though the paramagnetic Curie temperature (θp) is negative indicative of antiferromagnetic ordering, the large magnitude (-250 K) of θp reveals complex nature of the magnetism in this compound. Ru ions appear to be in the pentavalent state. We note that the Néel temperature undergoes only a marginal reduction by Y substitution. All these compositions are found to be insulators and thus the electron doping does not result in metallicity. Thus the overall magnetic and transport behaviour are found to be essentially insensitive to Y substitution for Ca, a finding which may favour the idea of quasi-one-dimensional magnetism in these compounds. |
