Ne and Mg isotope chains are investigated based on constrained calculations in the framework of a deformed relativistic meanfield (RMF) model with the NL075 parameter set. The calculated quadrupole deformation and binding energy are compared with other theoretical results as well as the available
experimental data. It shows that the calculated deformations of Ne and Mg with the NL075 are more accurate than those obtained with the NLSH. It is predicted that ^{19,29,32}Ne and ^{20,31}Mg maybe
have a triaxial deformation and ^{2528}Ne and ^{2730}Mg exhibit a shape coexistence probably. The closure effect of neutron number N=8 for ^{20}Mg is predicted to be very weak.
