Physical properties of V7O13 single crystals

View publication

Abstract

Heat capacity, resistivity, thermoelectric power, and magnetic susceptibility studies are reported for single crystals of V7O13 obtained by chemical-vapor-transport techniques. The entropy change accompanying magnetic ordering effects at 43.5 K is well below the values calculated on the basis of charge differentiation. Electrical and susceptibility anomalies are in accord with theoretical predictions for the prevalence of antiferromagnetic order below 43.5 K. A change in sign of the Seebeck coefficient as well as sharply dropping resistivity with decreasing temperature below the Néel temperature suggests the presence of two bands at the Fermi energy. © 1982 The American Physical Society.
