β¦ Synopsis
The dynamic susceptibility of the Ising reentrant spin glass system Fe,, Mn 9.38 Ti03 has been investigated using a SQUID magnetometer. The ac susceptibility was measured in the frequency interval 5 x 10m3 -2 x ld Hz. The data have been analyzed assuming critical slowing down, yielding a transition temperature TRsc = 26.8 K , a dynamic exponent zv = 8.2 and an order parameter exponent p = 0.55. Also, the wait time dependence of the zero field cooled magnetization was studied.

We consider an enlarged phase space of the +J spin glass which includes the dilute Ising model and the frustrated system. The three orthogonal axes in this space are: (i) The fraction of ferro-to antiferro-magnetic bonds, p; (ii) the ratio of the strengths of the antiferro-to ferromagnetic interatio
