We report an investigation of the higher-order magnetic susceptibilities, measured across a low-temperature metastable magnetic phase transition in La0.46Sr0.54Mn0.98Cr0.02O3. Measurements of the second- and third-order magnetic susceptibilities clearly indicate that this re-entrant transition is associated with the emergence of a finite spontaneous magnetisation as in a canted antiferromagnet. The large relaxation time scales seen in this system probably originate from self-generated clusters which arise as a consequence of Cr substitution in the host antiferromagnetic lattice.
