Spin dynamics of nanoparticle La_{0.7}Ca_{0.3}Mn_{0.7}Fe_{0.3}O_3 system was studied through the set of diverse magnetic measurements. Analysis of the data obtained from magnetic relaxation measurements, memory effect and AC susceptibility experiments pointed to a spin glass like behavior of interacting nanoparticle system.
