ELECTRICAL AND MAGNETIC PROPERTIES OF POTASSIUM TUNGSTEN BRONZE AND RUBIDIUM TUNGSTEN BRONZE,
Abstract
Single crystal conductivities were measured for K.4W03 and Rb.32W03 in the range 150 to 370 K. Carrier mobilities, which are somewhat higher than in the Li and Na tungsten bronzes, closely follow a T sinh squarred (theta/2T) dependence. Calculations on the basis of the theory of Howarth and Sondheimer strongly support the assumption that the thermal part of the carrier mobility in the tungsten bronzes is primarily determined by polar scattering from optical mode lattice vibrations. Magnetic susceptibilities were also measured at room temperature for Rb.26W03 and K.23-.45W03. Results are as pre as predicted by the Pauli-Peierls theory for quasi-free electrons. (Author)
