Abstract
We have directly observed well-separated Josephson vortex splinters with unquantized magnetic flux at asymmetric 45° grain boundaries in YBa2Cu3O7-¿ films by imaging magnetic flux with scanning SQUID microscopy. The existence of these splinter vortices has been predicted and is well described by a model based on dx2-y2 pairing symmetry and facetting of the grain boundary on a length scale shorter than the Josephson penetration depth.
