Abstract The magnetic properties of Nd_2(Fe_(1-x)M_x)_(14)B (M=C, Si) compoundshave been investigated. Substituting Fe by a small amount of metalloid C and Siatoms, the compounds are in tetragonal structure and have uniaxial anisotropy. Thesubstitution of C for part of Fe makes the Curie temperature and the intrinsic coer-civity of bond samples decrease at low temperature. The replacement of Fe by Simakes the Curie temperature increase with a maximum at the vicinity of x=0. 15.When the range of the content of Si is 0≤x≤0.10, the coercivity distinctly in-creases at room temperature, from 62.7 kA/m at x=0 to 138.7kA/m at x=0.06, wherethe residual magnetization has a maximum; at the mean time the saturation magne-tization decreases only by a small amount.
