| 中文摘要 | The structure and magnetic properties of SmMn2(Ge1-xSix)(2) compounds (x=0-1.0) have been investigated. All the compounds crystallize in ThCr2Si2-type structure. Substitution of Si for Ce leads to a linear decrease of the lattice constants and the unit-cell volume. In all compounds a transition from the ferromagnetic to the antiferromagnetic state is observed at a lower temperature T-1, which first decreases, goes through a minimum at x=0.4-0.6, and then increases again with Si concentration. As temperature increases, for the compounds with x<0.3 both a antiferromagnetic-ferromagnetic transition and the ferromagnetic-paramagnetic transitions are observed as well at T-2 and at the Curie temperature T-c, respectively. With increasing Si content the T-c decreases, whereas T-2 increases from 140 K for x=0 to 215 K for x=0.2. For compounds with x greater than or equal to 0.3 the antiferromagnetic-paramagnetic transition was observed with increasing temperature and the Neel temperature increases with increasing Si content. The saturation magnetization at 1.5 K decreases first, goes through a minimum at x=0.6, and then increases again with increasing Si content. At room temperature, the saturation magnetization decreases monotonically from 3.27 mu(B)/f.u. for x=0 to nearly zero for x=0.3. (C) 1996 American Institute of Physics. |
