(a) ZFC M ( H ) isotherms of Pr(Fe_0.4Co_0.6)_1.88C_0.05 at T = 2.0 K in a normal sweep and in an interrupted sweep. Two magnetic fields of 8 kOe and 10 kOe are maintained for 50 min in interrupted sweep. The inset shows the magnified jumps. (b) and (c) The corresponding time revolution of isothermal magnetization during the waiting time in interrupted sweep. The green thick lines represent the stretched exponential fittings.
