Observation of Yu-Shiba-Rusinov States and Inelastic Tunneling Spectroscopy for Intramolecule Magnetic Exchange Interaction Energy of Terbium Phthalocyanine (TbPc) Species Adsorbed on Superconductor NbSe₂.

ABSTRACT: We investigated the spin properties of the terbium phthalocyanine (TbPc) species adsorbed on the superconductor NbSe₂ surface using scanning tunneling microscopy and spectroscopy. TbPc₂ is a molecule in a class of single-molecule magnets (SMMs), and the use of superconductor electrodes attracts attention for the application to the devices using the spin degree of freedom. TbPc is a building block of TbPc₂ and can reveal the spin component's behavior. In the experiment, TbPc species were placed on the surface of the superconductor NbSe₂. We measured Yu-Shiba-Rusinov (YSR) states caused by the interaction between the superconducting state and magnetic impurity and inelastic tunneling spectroscopy (IETS) for the spin excitation, below 1 K. We also m
