Magnetic anisotropy of cerium endohedral metallofullerenes

Article Abstract:

Cerium endohedral metallofullerene (Ce@C82) is a pi-f composite nanomagnet, where anisotropic f-electron spin is expected to couple with the rotational motion of the fullerene cage that has pi-electron spin. The magnetic properties of Ce@C82 using the field-induced change in the magnetic susceptibility of organic solutions of Ce@C82 and the temperature dependence of the magnetic susceptibility and magnetization of Ce@C82 solid films are investigated.

Selective high-yield catalytic synthesis of terbium metallofullerenes and single-wall carbon nanotubes

Article Abstract:

Tb-metallofullerenes and single-wall carbon nanotubes (SWNTs) are selectively synthesized with dc arc discharge under 50-200 and 600 Torr helium atmosphere, respectively, by using Tb/Ni/C composite rods as anodes. Based on the high yield synthesis of metallofullerenes, five isomers of Terbium(Tb)@C(sub 82) are produced and four of them are isolated for the first time by multi-stage high performance liquid chromatography.

Temperature-dependent EPR studies on isolated scandium metallofullerenes: SC@C82(I, II) and Sc@c84

Article Abstract:

The isolation and electron paramagnetic resonance characteristics of two isomers of Sc@C82(I,II) and a major isomer of Sc@C84 are reported. The reasons for the large difference of the anisotropic g tensors is due to a difference in excitation energies of the unpaired electron spin of each Sc@C82 isomer.
