We have investigated the electronic and magnetic properties of $(3, 3)$ and $(4, 4)$ single-walled carbon nanotubes (SWNTs) filled with 3d transition metal (TM) monatomic chains, using first-principles calculations based on the density functional theory to get a thorough understanding of metal atom-filled carbon nanotubes. We have found that the magnetic moment of 3d TM-filled SWNTs decreases when the TM atom changes from smaller atomic radius to larger atomic radius or, when the diameter of the SWNT decreases. Specifically, the magnetic moment increases as the bonding strength between a TM atom and carbon atoms decreases.
