What are Hyperfine Interactions?
Hyperfine interactions refer to the small shifts and splittings in the energy levels of atoms, molecules, or solids due to the interactions between the nuclear magnetic moments and the electronic magnetic moments. These interactions are crucial in understanding the fundamental properties of materials at the
nanoscale.
Why are Hyperfine Interactions Important in Nanotechnology?
In
nanotechnology, the properties of materials can differ significantly from bulk materials due to quantum effects, surface effects, and size confinement. Hyperfine interactions provide critical insights into these properties by allowing the study of local magnetic fields, electronic environment, and atomic-scale interactions.
