Linear and nonlinear ac susceptibility of the canted-spin system: Ce(${\mathrm{Fe}}_{0.96}$${\mathrm{Al}}_{0.04}$${)}_2$

The linear and nonlinear ac susceptibilities of the canted-spin system Ce(${\mathrm{Fe}}_{0.96}$ ${\mathrm{Al}}_{0.04}$ ${)}_2$ have been measured using the mutual-inductance-bridge method as a function of temperature (50–100 K), frequency (19–1370 Hz) with different static biasing fields (12–36 Oe) as well as ac fields in the range of 4 to 24 Oe. An attempt has been made to compare the ‘‘canted-spin’’ system with the so-called ‘‘reentrant spin-glass system’’ from the ac-susceptibility point of view, since the ‘‘canting’’ plays a significant role in the reentrant spin-glass system, below the Curie temperature.
