Abstract

The magnetic properties of transition-metal based quasi-one-dimensional molecular metals show unusual concentration and temperature dependence. The ion magnetization in the chain formed by the metal spine of Cu1-cNic(pc)I phthalocyanine iodide was modeled by Monte Carlo methods, using dipolar, direct, and indirect exchange interaction potentials of variable range. The effects of dilution of Cu spin moments by diamagnetic Ni ions and impurity scattering effects on the electron gas polarization are determined. The results are compared with magnetic susceptibility measurements for this molecular metal.
