The long spin-relaxation time and large magnetic anisotropy of single-molecule magnets (SMM) render them potential candidates for next-generation recording elements. As SMMs are supported on substrates, a neutral charge is preferable as it can prevent the impurities originating from the counter ions. Neutral complexes, such as double-decker bis(phthalocyaninato) terbium(III) ([Tb(Pc)2]) and yttrium(III) ([Y(Pc)2]) complexes, were successfully supported onto a Au (111) substrate, and Kondo peaks were observed on the surface. However, the interactions between the complexes and the Au (111) surface are under investigation. Here, the interactions between [Y(Pc)2] and Au (111) surface are investigated using the density functional theory (DFT).
