1. At the end, both point defects and dislocation loops remain. 2. Point defects can nucleate reversed domains in ferromagnets and dramatically affect their coercivity.3. These irregularities are point defects and line defects. 4. Grain boundaries also cause deformation in that they are sources and sinks of point defects . 5. It is the simplest point defect . 6. There are three main point defects . 7. This can be extended to find the equilibrium concentration of other types of surface point defects as well. 8. Charged impurity ions and point defects have scattering cross-sections that are much greater than their neutral counterparts. 9. A point defect is an irregularity located at a single lattice site inside of the overall three-dimensional lattice of the grain. 10. While point defects are irregularities at a single site in the crystal lattice, line defects are irregularities on a plane of atoms.
