title: Magnetic moments and exchange coupling in nitride clusterfullerenes Gd(x)Sc(3-x)N@C80 (x = 1-3).
abstract: The magnetic properties of nitride clusterfullerenes GdxSc3-xN@C80 (x = 1-3) are studied as a function of the number of Gd atoms in the cluster. The intracluster interaction of the Gd ions in Gd2ScN@C80 and Gd3N@C80 is ferromagnetic with exchange constants of -1.2 K ± 0.1 K and -0.6 K ± 0.1 K, respectively. At 2 K, the magnetization curves exhibit noticeable deviations from the Heisenberg model pointing to a non-negligible anisotropy.
