Abstract
The static and dynamic features of magnetization are investigated using dc magnetization and ac susceptibility measurements on La1−δMn0.7Fe0.3O3 for δ = 0 and 0.13. The results indicate that short range ferromagnetic clusters coexist with the glassy magnetic state. The analysis on the frequency dependence of spin freezing temperature (Tf) using the Vogel–Fulcher law and the dynamical scaling behaviour near Tf indicates that the spin freezing temperature behaves like a spin-glass transition temperature for both the compounds. The cluster-glass states of both the compounds exhibit similar characteristic features.
