Ni@B80: A single molecular magnetic switch
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 confi...

The electronic and magnetic properties of zigzag zinc oxide (ZnO) nanoribbons with or without hydrogen passivation are investigated using ab initio calculations. The ribbon is found to be half-metallic ferromagnet when edge zinc atoms are passivated only. Moreover, the half-metallicity only emerges in the ribbons with relatively large width. Besides, the half-metallic ferromagnet can also be achieved when the passivatator H is replaced by CH3 or NH2. These diverse electronic and magnetic properties might open ZnO materials great possibility in future spintronics. ©2009 American Institute of Physics
