摘要	Dimensionality is one of the most important parameters in the determination of the physical properties. Therefore, tuning of effective dimensionality is of significant importance for modulating the functionality of materials. In this work, we find that the spin-dimensionality can be changed by Co-doping in the Fe1-xCoxSi system. Investigation of the critical behavior shows that the effective critical exponents for x = 0.3 agree with the three-dimensional (3D) Heisenberg model with {d : n = 3 : 3} (d is the spatial-dimensionality, and n is the spin-dimensionality). With the increase of Co-content, the effective critical exponents for x = 0.5 fulfill the 3D-XY model with {d : n = 3 : 2}, while those for x = 0.6 approach the 3D-Ising model with {d : n = 3 : 1}. These results indicate the lowering of the spin-dimensionality with the increase of Co-content in Fe1-xCoxSi. We suggest that the modulation of the spin-dimensionality in Fe1-xCoxSi should result from the enhancement of the anisotropic magnetic interaction induced by the doping of Co.
