Spin Torque and Zeta Force in Allene-Type Molecules

Abstract

The spin torque, the zeta force, and the zeta potential, which are significant quantities to describe the local picture of spin dynamics, are studied by using allene-type molecules (C3H4 and C3H2Li2) in their stationary states. We show that the two molecules have different distribution patterns of these quantities though their structures are very similar to each other. It is also shown that the zeta potential distribution is almost independent of the electron density distribution.
