Sažetak
Single crystals of AM05O3 (A = Ca, Sr, La-Gd), suitable for electrical conductivity measurements have been grown by high temperature and fused salt electrolytic techniques. The structures of all of these compounds are dominated by the presence of bi-octahedral clusters of Mo atoms joined together parallel to the monoclinic a axis, forming infinite chains. Temperature dependent electrical resistivity measurements on AMo5Og (A = La, Ce, Pr, Nd, Sm) show anomalous metal-semiconductor transitions near 180 and 30 K.
The resistivities of the Eu and Gd analogues are different, in that the former is semiconducting while the latter shows a weak anomaly ~ 110 K. The Ca and Sr analogues are also semiconducting in the range 20-300 K. The electrical conductivity of these phases appears to be closely related to the inter-cluster separation and the number of metal-cluster electrons. The magnetic susceptibility of these compounds show no anomalies at the temperatures corresponding to the transitions seen in their electrical resistivities. The magnetic susceptibility of LaMosOg shows a small decrease in the \!y (dy/dT) vs T plot in the vicinity of ~ 150 K.
