Abstract
Magnetic fields penetrate a type-II superconductor via quantized Bur lines. Why these flux lines sometimes form square arrays, as in YNi2B2C with the field parallel to the c axis, rather than the expected hexagonal ordering, has long fascinated physicists and has eluded a simple explanation. Our latest measurements on YNi2B2C prove conclusively that the London penetration depth within the a-b plane is not isotropic. This anisotropy of the London depths implies that the cross section of an individual flux line has square symmetry, which makes a square lattice energetically favored over the more prosaic hexagonal ordering.
