We present a study of the charge order of 214 stripe ordered superconducting cuprates (La1.6-xNd0.4)SrxCuO4 and La2-xBaxCuO4 for doping levels 0.11≤p≤0.14 by means of resonant x-ray scattering. Up to 6 T, we find no field dependence on either the integrated intensity or the correlation length of the charge modulations, providing evidence for strong stability of charge order under applied fields. The magnetic field data support a strong pinning scenario induced by the low-temperature tetragonal distortion and static disorder, and they highlight the role of the symmetry of the lattice on the stabilization of electronic periodicities.
