Abstract: | The systems RM6Al6 were studied by X-ray, magnetization and Mossbauer spectroscopy (57Fe and 151Eu) measurements. The RCu6Al6 which crystallize in the f.c.c. NaZn13 structure order ferromagnetically at low temperatures (Tc = 16KforR = Eu). The RMn6Al6 systems which crystallize in the rhombohedral Th2Zn17 structure order antiferromagnetically (and Eu). LaFe6Al6 has the NaZn13 structure and orders antiferromagnetically at a relatively low temperature, 38K. The correlation of crystal structure and magnetic properties of these systems and those of RM6Al6 (R = heavy rare earth, tetragonal ThMn12 structure) are discussed. |
