The present study reports the effect of rare earth doping on the structural and magnetic properties in the Ca2-xLnxMnO4, where Ln=Nd and Sm Ruddlesden Popper-type. The studied specimens were synthesized as powder samples by solid state reaction at high temperature. The analysis by powder X-ray diffraction using Rietveld refinement showed the crystallization in the tetragonal system for all compounds. The magnetic measurements were studied as a function of temperature (T = 2–300 K). When the temperature decreases, each compound has shown first a ferromagnetic–paramagnetic (FM–PM) transition and then an antiferromagnetic–ferromagnetic (AFM–FM) one. The transition temperatures are found to be rare earth doping dependent. For all compounds, a spin-glass phenomenon is evidenced by FC/ZFC magnetization curves.
