(a) dc magnetic susceptibility versus temperature for x -(100-x) TNT, where (x = 2, 5, 7); (b) The magnetization versus the applied field curves (M versus ) of 2% Gd3+-98 TNT at 10 K (as a representative example); as well as (c) and (d) Temperature dependence of the entropy change for different mole percent of -TNT under an external magnetic field equal to 400 Oe.
