The reentrant Ising spin glass Fe0.62Mn0.38TiO3 has been investigated using SQUID magnetometry. The system is antiferromagnetic below T(N)(H = 0) = 33 K, and enters a mixed antiferromagnetic/spin glass phase below T(g)(H = 0) = 25.8 K. Within the concept of a recent mean field model, a ratio T(N)(0)/T(g)(0) close to unity indicates both intra- and interlayer frustration. The existence of an overlap length, l(DELTA-T), below which equilibrium spin correlations at temperatures T and T + DELTA-T are indistinguishable has been verified by magnetic relaxation experiments on this spin glass system.
