Using small-angle neutron scattering (SANS), we found that the high-density of crystal defects induced via high-pressure torsion (HPT) straining cause a significant spin-misalignment scattering in pure Ni. The analysis of the correlation length of the spin misalignments provided that the spin misalignments surround the defect with the size of 11 nm in HPT-strained nickel.
