“…Magnetic susceptibility is a considerable magnetic parameter to think about the interaction between CuPc and Co. But the magnetic susceptibility of polymeric CuPc was reported to be order of 10 À2 at 5 K, 23) which was 4 orders of magnitude smaller than that of the Co estimated from the calculation of M-H curve in our study, so we concluded that the magnetic susceptibility of the CuPc could not be considered on the mechanism of spin states.…”

We have fabricated a series of copper-phthalocyanine–cobalt (CuPc–Co) nanocomposites (compositional ratio of CuPc:Co=4:1), wherein Co nanoparticles were embedded within a CuPc matrix, in order to study the spin transport properties and to investigate spin–spin interactions between conducting spins and localized spins in the CuPc. Nonlinear characteristics of electric current, I–V (2N-1), (V: bias voltage, N: order of co-tunneling) were observed, where the fifth order co-tunneling was clarified. The order of the co-tunneling effect in CuPc–Co was almost equal to that in a rubrene–Co nanocomposite with almost the same diameter of the Co nanoparticles. We have not found clear evidence of spin-flip processes, as observed in other molecular systems, which may be attributed to the spin-coupling between localized spins in the CuPc and spins in Co.
