Abstract
  • Proving the preservation of functionality at the molecular scale is still a major challenge, both for the choice of suitable derivatives and protocols and for the employed experimental tools and methods. By using a combined scanning probe (AFM and STM) and spectroscopic methodology (XPS, XAS and XMCD), it is shown that Gd4M8 derivatives (with M = Zn2+, Ni2+) are robust molecular units which preserve their electronic, magnetic, and thermodynamic properties when deposited on a metallic surface. Namely, entropy variation ?S = [S(6 T) - S(0 T)] exceeding 8 R (20 J kg-1 K-1) at 4 K in isolated Gd4Ni8 molecules dispersed on Au(111) surface is measured and a viable route to exploit large magnetocaloric effect at single molecule level is shown.
