Recently, a striking positive effect of tiny Zn doping on crystal growth quality has been found in melt-textured (Nd, Eu, Gd)Ba_2Cu_3O_y pellets. The material could be easily grown from MgO seed, possessing a rather high lattice mismatch to the superconducting compound. In the present work we study spatial distribution of local magnetic properties and chemical composition of a (Nd_{0.33}Eu_{0.38}Gd_{0.28})Ba_2Cu_3O_y + 0.035 mol% Zn pellet. The plane cutting the pellet into two halves along the symmetry axes of the opposite a-axis growth sectors is investigated. While the chemical composition only slightly fluctuates, magnetic properties show quite an interesting spatial variation.
