Giant exchange coupling and field-induced slow relaxation of magnetization in Gd2@C79N with a single-electron Gd–Gd bond

Author affiliations

Abstract

Magnetic properties of the azafullerene Gd2@C79N are studied by SQUID magnetometry. The effective exchange coupling constant jGd,e between the Gd spins and the spin of unpaired electron residing on the single-electron Gd–Gd bond is determined to be 170 ± 10 cm−1. Low temperature AC measurements revealed field-induced millisecond-long relaxation of magnetization.
