(a) The temperature dependence of magnetization for (x = 0.05, 0.075, 0.10, 0.125, and 0.15) measured under field-cooled and zero-field-cooled conditions with an external field ∼100 Oe. (b) The plot of versus temperature for (x = 0.05, 0.075, 0.10, 0.125, and 0.15). (c) The plot of versus temperature for (x = 0.05, 0.075, 0.10, 0.125, and 0.15). (d) Isothermal magnetization for (x = 0.05, 0.075, 0.10, 0.125, and 0.15) at 2 K.
