Abstract
Magnetic properties of amorphous DyxFe1-x (x = 0.15, 0.21, 0.25) with the random anisotropy and exchange were investigated by the measurements of magnetization and Hall effect vs. temperature and external field H. Speromagnetic behavior was shown in all samples measured for H = 1 kOe. A reentrant phenomenon from ferrimagnetic to speromagnetic behavior was observed for x = 0.25 with coherent perpendicular anisotropy. At H = 12 kOe, all samples show ferrimagnetic behavior.
