In this report we investigate changing of magnetic properties of system (La1–zNdz)1,4Sr1,6Mn2O7 during isovalent substitution from lanthanium to neodymium at different concentration z = 0, 0.3. Decreasing of Mn-Mn in-plane distance with increasing z leads to the suppression of the ferromagnetic state that, as expected, tells us about the change of the orbital character eg – electrons with d3z2-r2 on the dx2-y2. Also, at high applied magnetic fields metamagnetic transition observed at concentration z = 0.3, it is characterized by a sharp increase of the magnetization and the change of the ground state of the sample from the antiferromagnetic to ferromagnetic.
