Abstract

TbPc2 single-molecule magnets adsorbed on a magnesium oxide tunnel barrier exhibit record magnetic remanence, record hysteresis opening, perfect out-of-plane alignment of the magnetic easy axes, and self-assembly into a well-ordered layer.

Keywords: X-ray absorption spectroscopy; scanning tunneling microscopy; single-molecule magnets; surfaces.
