Low-field dc-magnetization and thermoremanent-magnetization measurements have been recorded from the rutile-related iron antimonate of composition

. The zero-field-cooled susceptibility curve at low magnetic fields (H=20 Oe) shows a small peak at ∼72 K and a much broader peak at lower temperatures of ∼25 K. The temperature dependence of the remanent magnetization below ∼72 K indicates the existence of two different relaxation regimes which depend on the strength of the applied field in which the sample was cooled. The thermoremanent-magnetization measurements as a function of time show aging effects and the characteristic parameters are quite similar to those found in canonical spin glasses. The temperature dependence of the first nonlinear coefficient

The moderate degree of frustation associated with an inhibited antiferromagnetic transition at ∼72 K, is nevertheless insufficient to produce a true spin-glass transition where the magnetic correlation length is even much shorter.
