چکیده انگلیسی
We have studied the effects of Co substitution for Mn on the structure and magnetic properties of the HoMn6âxCoxSn6 compounds (0⩽x⩽0.25) with HfFe6Ge6-type structure (space group P6/mmm) by X-ray powder diffraction and magnetization measurements. A monotonic decrease of the lattice parameters a and c is observed with increasing Co content. While the compounds with x=0 and 0.05 exhibit ferrimagnetism in the whole temperature range, the compounds with 0.1⩽x⩽0.15 show ferrimagnetism, helimagnetism and re-entrant ferrimagnetism with decreasing temperature. For the compounds with x=0 and 0.05, the spin reorientation temperature is observed. A metamagnetic transition from helimagnetic magnetic ordering to ferrimagnetism is observed for the compounds with x=0.1 and 0.2. The results are summarized in the HoMn6âxCoxSn6 magnetic phase diagram.
