Abstract

We analytically treat model Λ-processes driven by chirped lasers. The obtained results (consistent with previous numericalfindings) bring insight into the microscopic origin of the ERASE functionality via frequency detuning in the presence of chirp, and explain the pertinent differences in the magnetic-switching behavior at Fe, Co and Ni atoms.
