Query: Predicted giant magnetic moment on non-{n0m} surfaces of d-wave
  superconductors --- Can it be observed and how?   It has been noted previously that the sizable areal density of midgap states
which must exist on any non-{n0m} surface of a d-wave superconductor can lead
to a giant magnetic moment. Here we show that this effect is observable, and
discuss two precise ways to observe it: (i) by directly measuring magnetic
moment in a system with a large density of internal {110} surfaces, or (ii) by
performing spin-polarized tunneling on a {110} surface. In both cases a
sufficiently large magnetic field should be applied in the [1$\bar 1$0]
direction.
