Spin-Atomic Vibration Interaction and Spin-Flip Hamiltonian of a Single Atomic Spin in a Crystal Field

Satoshi Kokado, Kikuo Harigaya, Akimasa Sakuma

We derive the spin-atomic vibration interaction $V_{\mathrm{SA}}$ and the spin-flip Hamiltonian $V_{\mathrm{SF}}$ of a single atomic spin in a crystal field. We here apply the perturbation t…
