%X The structural, magnetic and electric properties of Pr1 xSr1+xCoO4 layered perovskite have been investigated systematically over the range of doping, 0 ¡Ü x ¡Ü 0.40. The Rietveld refinements of x- ray powder diffraction (XRD) patterns at room temperature indicate that the samples crystallize in the K2NiF4 -type structure with group symmetry I4/mmm. The samples of 0 ¡Ü x < 0.20 show Curie-Weiss paramagnetic behavior. With increasing x (0.20 ¡Ü x ¡Ü 0.40), three magnetic transition temperatures can be identified. The ground state exhibits a spin glass (SG) phase below the spin glass transition temperature TSG . Above, there is a mixture of ferromagnetic (FM) and antiferromagnetic (AFM) short-range order for TSG< T < TM with TM denoting the temperature of the corresponding anomaly in the magnetic susceptibility data. The third state can be attributed to a Griffiths phase for TM < T
