The magnetic properties of the spin glass La FeyNi5-y (0.5≤y≤1.1) are reported. The spin freezing temperatures, Tf, in these alloys have been measured. It is observed that at lower temperatures there is a transition from the paramagnetic (PM) to the ferromagnetic (FM) phase for y≤0.9 and the Fe-content dependence of the freezing temperature is approximately linear. There is a transition from the PM to the FM and from the FM to spin glass phase for y≥1.0.
