Physical Review B
We study vortex lattices (VLs) in superconducting weak-pinning platelet-like single crystals of β−Bi2Pdin tilted magnetic fields with a scanning tunneling microscope. We show that vortices exit the sample perpendicular to the surface and are thus bent beneath the surface. The structure and orientation of the tilted VLs in the bulk are, for large tilt angles, strongly affected by Coulomb-type intervortex repulsion at the surface due to stray magnetic fields.
