Research Abstract

I found that FePc monolayer on Au(111) has a Kondo lattice feature by low temperature STM with strong magnetic field. An FePc molecule on Au(111) shows Kondo resonance in the dI/dV spectrum, that is, DOS. In addition, FePc molecules form square lattice structure on the surface. In this study, I investigated the Kondo property of FePc on Au(111)(Kondo temperature T_K=2. 6K), and the formation of the lattice structure by controlling the coverage. FePc Kondo lattice shows not the heavy Fermion phase but the antiferromagnetic order phase from the spatial distribution of the Kondo cloud. This is caused by the stronger intermolecular RKKY interaction than the Kondo coupling between an FePc and the Au substrate. Next, I investigate the FePc manipulation. By using STM tip, the position of an FePc molecule can be changed. And by additional coordination of a CO and an NO molecules, the Kondo feature of the FePc is drastically changed. These methods were also applied to the lattice system(FePc monolayer).
