Magnetization dynamics in the density matrix formalism

  title={Magnetization dynamics in the density matrix formalism},
  author={Benjamin Assouline and Amir Capua},
Magnetization dynamics are pivotal to the field of spintronics, as magnetization switching is prominent to MRAM technology. The LLGS equation that dominates magnetization dynamics can be reformulated by the generic equations of two-level quantum systems. Yet, the analogy between magnetization and two-level dynamics is still elusive to date. In this paper, we present a rigorous mathematical derivation of magnetization dynamics using two-level density matrix formalism. Specifically, we formulate…
