Özet
The crystal structure and magnetic properties of the R3Co29Ge4B10 (R = Ce, Pr, Nd, Sm, Gd, Dy) borides have been studied by X-ray powder diffraction (XRPD) and magnetization measurements. All compounds crystallize in a tetragonal crystal structure with the space group P4/nmm. Ferromagnetic behavior is observed for the R3Co29Ge4B10 compounds with light rare earth elements (Ce, Pr, Nd, Sm). The R3Co29Ge4B10 borides consisting of heavy rare earth elements (Gd, Dy) are ferrimagnets with the compensation temperatures of 120 and 82 K, respectively. The Curie temperatures are between 191 and 236 K.
