Electrical Conduction in Transition-Metal Salts

Abstract

Abstract We predict that a given transition-metal salt as, for example, a K2CuCl4·2H2O–type compound, can behave as an electrical conductor in the paramagnetic case. In fact, we determine the electrical conductance in a salt of this type. This conductance is found to be quantised in agreement with previous well-known results. Related mathematical expressions in the context of superexchange interaction are obtained. In addition, we determine the corresponding (macroscopically viewed) current density and the associated electron wave functions.
