. It is found that the encapsulated Con clusters inside C60 and C82 cages are energetically

favorable except for Co7@C60. The encapsulation does not change significantly the structure of the

enclosed clusters, but the magnetic moment...

of iron atoms (n) while those of the

Fen@C80 are negative and their absolute values increase up to n¼6. The encapsulation does not

significantly change the enclosed cluster structure, but the total magnetic moment of the larger clusters...
