We find that each Fe adatom generates a striking zero-energy bound state inside the superconducting gap, which do not split inmagnetic fields up to 8 T, underlining a nontrivial topological origin. Our findings point to magnetic Fe adatoms evaporated on bulk superconductors with topological surface states for exploring Majorana zero modes and quantum information science under field-free conditions.
