  We discuss recent elastic neutron scattering and scanning tunneling
experiments on high-T_c cuprates exposed to an applied magnetic field. In
particular we show that a physical picture consisting of antiferromagnetic
vortex cores operating as pinning centers for surrounding stripes is
qualitatively consistent with the neutron data provided the stripes have the
usual antiphase modulation. Further, we calculate the electronic structure in
such a region using a T-matrix method, and find a checkerboard interference
pattern consistent with recent scanning tunneling experiments.
