Abstract:

The geometric and magnetic properties of the MSn₁₂(M=La,Pr,Nd,Pm,Sm,Eu,Tb,Dy,Ho,Er,Tm,Yb,Lu)clusters were studied,using the relativistic density-functional method.The geometric optimization demonstrates that the exohedral stannaspherene MSn₁₂(M=La,Pr,Nd,Pm,Sm,Eu,Tb,Dy,Ho,Er,Tm,Yb)with C_3v symmetry and the endohedral stannaspherene Lu@Sn₁₂ with I_h symmetry are the most stable structures.Moreover,it is found that the magnetic moment of MSn₁₂ cluster varies from 0 μ_B to 7 μ_B by doping different lanthanide atoms,implying that the magnetic moment of the stannaspherenes can be tuned by doping the different lanthanide atoms.Our study further demonstrates that magnetic moment of NdSn₁₂ and PrSn₁₂ also can be tuned by the external electric field.
