摘要：

The vortex structure in the iron pnictide single crystals Ba1-x K (x) Fe2As2 and Sr1-x K (x) Fe2As2 of the 122 type and SmFeAsO1-x F (x) of the 1111 type has been investigated using the decoration method. In all of the crystals under investigation, no regular vortex lattice has been revealed in the magnetic field range up to 200 Oe. The disordered vortex structure is discussed in view of the vortex pinning in single crystals.
