Giant exchange coupling and field-induced slow relaxation of magnetization in Gd(2)@C(79)N with a single-electron Gd–Gd bond

Magnetic properties of the azafullerene Gd(2)@C(79)N are studied by SQUID magnetometry. The effective exchange coupling constant j(Gd,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 measureme...

Sumario:Magnetic properties of the azafullerene Gd(2)@C(79)N are studied by SQUID magnetometry. The effective exchange coupling constant j(Gd,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.
