Abstract: Structural and magnetic properties of pure and Zn doped NdMnO<subscript>3</subscript> manganites have been investigated using neutron diffraction and ac susceptibility measurements. The partial replacement of Mn<superscript>3+</superscript> by Zn results in the modification in the magnetic behavior of NdMnO<subscript>3</subscript> at low temperature. Temperature dependent ac susceptibility measurements show a broad hump like behavior around ~ 60 K suggesting the presence of antiferromagnetic ordering. Temperature dependent ND studies on NdMn<subscript>0.95</subscript>Zn<subscript>0.05</subscript>O<subscript>3</subscript> sample revealed the evolution of antiferromagnetic order around ~ 75 K, evident from the emergence of (010) Bragg reflection. The intensities of (101) and (111) Bragg peaks in ND patterns increases below 75K which has been attributed to the presence of ferromagnetic (FM) component, getting enhanced at low temperature. Results of the temperature dependent ND and ac susceptibility measurements on NdMn<subscript>0.95</subscript>Zn<subscript>0.05</subscript>O<subscript>3</subscript> have been discussed in detail.
