Magnetic Fields (IMAGE) National University of Singapore Caption Image of the magnetic fields recorded by scanning a tiny superconducting coil over the surface of a LaMnO3 film grown on a substrate crystal. The magnetic left-hand side is seven LaMnO3 blocks thick (about 3 nm), while the nonmagnetic right-hand side is only five (2 nm). The measuring setup is shown on the right.
