Abstract
The magnetic properties of amorphous alloys with composition GdxLa72-xGa18B10 have been investigated using ac-susceptibilty and dc-magnetization techniques in the temperature range 4.2300 K. This system shows double-transition behavior for x67 and paramagneticspin-glass transition behavior for x<67. Time-dependent magnetization effects are present in the spin-glass phase and these effects vanish in finite fields, in qualitative agreement with mean-field theory. The magnetic isotherms around both the paramagnetic-ferromagnetic and ferromagneticspin-glass transitions scale according to the scaling hypothesis, and these results are discussed in some detail. A magnetic phase diagram for this system is obtained from the transition temperatures determined from scaling.
