Özet
The crystal structure and magnetic properties of the FeMn 1-xNixGe (0≤x≤1) compounds have been studied by room temperature X-ray powder diffraction and magnetometric measurements within the temperature interval of 5-400 K and for magnetic fields up to 5 T. All compounds crystallize in a hexagonal Ni2In-type crystal structure with space group P63/mmc and show ferromagnetic behavior. It has been found that the temperature of magnetic ordering (TC) increases nearly linearly with increasing Ni concentration from 163 K (x=0) to 304 K (x=0.4). Samples with x≥0.8 are ferromagnetically ordered above 400 K. The concentration dependency of the saturation magnetization at 5 K (MS) shows a maximum of MS=2.81 μB per formula unit for x=0.4. © 2012 Elsevier B.V.
