Abstract
The magnetic and structural study of Gd x Y 1-x LaAl 4 system was performed. The magnetic properties investigated in the 4–600 K temperature range and fields up to 80 kOe showed the ferromagnetic order for x≤0.8. For low gadolinium concentration, x≤0.4, the magnetic moment and the transition temperature values are lower than expected for Gd 3+ ion. It is considered that the dilution allows the formation of substitutional and atomic disorder, leading to modifications in the exchange interactions and determining a random-distribution configuration for gadolinium moments.
