- Description
- Magnetic properties of the Laves phase system <math>Ce(Fe_{1-\operatorname{x}}Al_\operatorname{x})_2</math> were investigated by means of magnetization and electrical resistivity measurements for <math>0.60 \le x < 0.90</math>. X-ray powder diffratograms reveal that at least up to 40% of iron in <math>CeAl_\operatorname{2}(x=0.60)</math> the samples are single-phase. A magnetic phase diagram is proposed where, in this range of concentration, the system changes from a ferromagnetic to a quasi ferrimagnetic phase around x = 0.80. At low temperatures the mixed phase character was indicated by spin-glass behaviour, walls pinning of ferromagnetic domains and frustration.
