Single Molecular Adsorption of Terbium(III) Bis-phthalocyaninato (TbPc2) Governed by Two Surface Reconstructions of Perovskite Type SrVO3 Epitaxial Ultrathin Film

Using low temperature scanning tunneling microscopy (STM), we observed a single molecule magnet, Tb3+ double decker molecule TbPc2 (Pc = phthalocyaninato), adsorbed on a perovskite type transition metal oxide SrVO3 ultrathin film. TbPc2 molecules adsorbed intact and flat on two surface reconstructions of SrVO3, (\(\sqrt{2} \times \sqrt{2} \))-R45° and (\(\sqrt{5} \times \sqrt{5} \))-R26.6°, with different configurations. High resolution STM images revealed that the adsorption configurations were governed by the adatom structure of each surface reconstruction according to the proposed adsorption configurations. Using low-temperature scanning tunneling microscopy, we observed a single molecule magnet, terbium(III) bis-phthalocyaninato (TbPc2), adsorbed on a perovskite type SrVO3 ultrathin film. TbPc2 adsorbed intact and flat differently on two surface reconstructions of SrVO3, (\(\sqrt{2} \times \sqrt{2} \))-R45° and (\(\sqrt{5} \times \sqrt{5} \))-R26.6°.
