The nanoindentation in out-of-plane domains of a {001} oriented single crystal was performed with a conical indenter of tip radius. The first pop-in occurs at load. The surface deformation was studied with atomic force microscopy and piezoresponse force microscopy. In addition to dislocation structures inside the remanent indentation, a rosette arm pattern is observed. The four identified screw arms are due to created -domains as well as to at the free surface emerging dislocations of the glide system. For parts of the screw arms, a detailed analysis of the domain and dislocation structure is presented.
