(a–e) Magnetization as a function of time at different temperature for all the alloys. Inset of (a) represents the relaxation behaviour of Fe2CrAl at 10 K. Solid red line depicts the logarithmic fit using Eq. 3. Note: Left axis represents the scale for data obtained at 2 K and right axis represents the scale for the data obtained at 10 K.
