Magnetization and NMR relaxation measurements in Lix(Mn,Zn)Pc were performed in order to study the evolution of the electronic properties of metal phthalocyanines upon electron doping. For x = 2 the doubly degenerate lowest unoccupied molecular orbital (LUMO) is half filled and the electrons are coupled in a singlet state owing to the Jahn–Teller distortions. The effects of the Jahn–Teller distortions on the spin excitations are discussed in the light of NMR relaxation measurements.

Abstract

Magnetization and NMR relaxation measurements in Lix(Mn,Zn)Pc were performed in order to study the evolution of the electronic properties of metal phthalocyanines upon electron doping. For x = 2 the doubly degenerate lowest unoccupied molecular orbital (LUMO) is half filled and the electrons are coupled in a singlet state owing to the Jahn–Teller distortions. The effects of the Jahn–Teller distortions on the spin excitations are discussed in the light of NMR relaxation measurements.
