We theoretically performed that the magnetic moment of Ni-encapsulated B80 (Ni@B80) can be greatly tuned by changing the position of Ni atom inside the hollow cage of B80. There are three stable configurations of Ni@B80 with Ni atom located at center, pentagon, and hexagonal-in, respectively. Compared with that of Ni@B80 with Ni atom located at center, all the magnetic moments of Ni@B80’s with Ni atom located at pentagon and hexagon-in in the hollow cage of B80 are zero. These fascinating findings imply that Ni@B80 may be a promising candidate for single molecular magnetic switch.
